Sound Property
Your Bitcoin. Your Home. No Compromise.
Sharia-compliant property finance for Bitcoin holders — a genuine co-ownership partnership in Dubai, without selling your Bitcoin, without interest, and without compromising your deen.
You Hold Bitcoin. You Want a Home. Nobody Will Help You.
You've held Bitcoin through drawdowns that shook out everyone around you. Your position is worth seven or eight figures. And you're still renting.
The Bank's Answer
Every bank in Dubai — conventional and Islamic — will tell you the same thing: they don't recognise Bitcoin as income, don't accept it as qualifying capital, and have no product for you. Your only conventional options are to sell at today's price, or keep renting and hope the system catches up.
The Hidden Problem with "Islamic" Mortgages
Products from DIB, ADIB, and Emirates Islamic are EIBOR-linked. Their rental returns track the interbank lending rate — not the property market. Their buyback prices are locked at origination. For anyone who examines the substance rather than the label, these products replicate conventional mortgage economics under a different name.
Sound Property exists because you shouldn't have to choose between your conviction in Bitcoin, your religious obligations, and owning a home for your family.
How It Works
Sound Property is a declining co-ownership partnership. You contribute Bitcoin. The fund contributes cash. Together, you purchase the property — and you acquire it fully, over time, on your terms.
1
Bitcoin as Genuine Equity
Your Bitcoin enters the partnership as capital at risk — not as collateral, not as a deposit. Both parties co-own the property and the Bitcoin, proportional to their contribution.
2
The Fund Buys the Property Now
No need to sell. No bank approval. No income documentation. You qualify on your Bitcoin holdings alone. The fund's cash secures the property immediately.
3
You Pay Market Rent — Falling Over Time
You pay rent only on the fund's share, indexed to the RERA Rental Price Index. As you acquire more of the partnership, the fund's share shrinks and your rent falls with it.
4
You Buy the Fund Out Over 5, 8, or 12 Years
At each scheduled tranche, the property is independently revalued by a RICS-certified appraiser. Bitcoin is valued at the 30-day VWAP. Pay in cash, appreciated Bitcoin, or any combination.
5
No Margin Calls. No Forced Liquidation.
If Bitcoin drops 80% tomorrow, nothing changes. You continue living in your home, paying rent, and buying out the fund on schedule. The partnership absorbs volatility proportionally.
6
Full Ownership at Term End
At the end of the term, you own 100% of your home. Free and clear. No debt. No ongoing obligation. Acquired through a structure designed from the ground up to be fully halal.
What Makes This Genuinely Different
This is not a conventional product with an Islamic label. The structural distinctions matter — and they are the reason scholars have endorsed this approach where it has been faithfully implemented.
"A genuine Islamic partnership carrying all of the justice and risk sharing that an Islamic contract should have, in a way which I have not seen in any of the other products currently available." — Scholar endorsement of PFIDA's equivalent structure, UK
Sound Property embeds the same structural principles inside a regulated ADGM fund — and extends them to Bitcoin holders for the first time.
The Monetary Foundation
Why Bitcoin Is Not a Gimmick
Sound Property's use of Bitcoin rests on a substantive argument about Islamic finance and the monetary system — articulated most rigorously by Harris Irfan, who co-founded Deutsche Bank's Islamic finance practice and spent two decades inside the industry.
When an Islamic bank extends a diminishing musharaka, the capital it deploys was itself created through lending — money conjured from nothing by a fractional reserve institution. The Bank of England confirmed in its 2014 Quarterly Bulletin that commercial banks create money simply by making loans. Irfan argues this ex nihilo creation is itself a form of riba, regardless of how carefully the contracts on top are drafted.
Sound Money, Sound Finance
Bitcoin cannot be created from nothing. Its creation requires proof of work — real energy, real computation, real cost. Its supply is finite and its issuance schedule is knowable for every point in the future. No central authority can inflate it. No bank can manufacture it through the act of lending.
The Islamic Golden Age — seven centuries of achievement — was built on the gold dinar, a sound money standard that encouraged genuine risk sharing. Irfan's thesis: Bitcoin has superior sound money characteristics to gold. As Irfan and Farrington conclude, Islamic finance "is what will naturally and necessarily emerge on top of Bitcoin."
Finite Supply
21 million Bitcoin. Fixed forever.
Proof of Work
Created through real energy and computation — never from nothing.
No Central Authority
No institution can inflate, confiscate, or manufacture it.
Superior to Gold
More scarce, portable, divisible, and verifiable.
The Structure: Four Independent Contracts
Sound Property is built on four contracts, each serving a distinct function and designed to align with AAOIFI Standards No. 9 and No. 12. Each contract is commercially related but contractually independent — a core AAOIFI requirement.
Musharaka
A co-ownership partnership over the property and Bitcoin. Both parties own undivided shares proportional to capital at risk. Profit and loss ratios match ownership percentages exactly.
Ijara
A lease of the fund's property share to you at market rent, indexed to the RERA Rental Price Index. As you acquire more of the partnership, the rent decreases proportionally.
Wa'ad
Your unilateral binding promise to purchase the fund's share at future market value — not a pre-stipulated price. Neither party knows the total return at signing. The fund can lose money.
BTC Settlement Facility
A separate arrangement between you and a licensed third-party OTC desk. The fund is not a party to the conversion. You always control whether and when to convert Bitcoin to settle tranche payments.

Each contract is valid independently — the musharaka is valid without the ijara; the ijara is valid without the musharaka. No contract is conditional on another. This independence is a core requirement under AAOIFI Standard No. 12.
The Numbers: An Honest Comparison
Entry tier: 13 BTC, AED 7M property, 12-year term. BTC at AED 300K. 20% BTC CAGR assumption. 3% property appreciation. Balanced cash and BTC payment mix.
We Will Be Straight with You
At 20% BTC CAGR, the person who holds 13 BTC and rents has a higher total AED position at Year 12. Sound Property does not claim to maximise net wealth above every alternative.
What the Numbers Don't Capture
That person owns nothing at Year 13. They continue paying rent, which has likely increased. The Sound Property co-owner owns an AED 10M home outright — no debt, no ongoing housing cost, acquired entirely through halal means. The gap is the price of homeownership. It is a trade many holders are willing to make.
Who This Is For
Sound Property is designed for ADGM Professional Clients holding a minimum of 13 BTC. The threshold ensures every co-owner has sufficient assets to absorb partnership mechanics across all scheduled buyout events, including scenarios where Bitcoin is flat or declining.
The Typical Co-Owner
You arrived in Dubai within the last few years from the GCC, Indian subcontinent, Pakistan, Turkey, Southeast Asia, or the UK. You hold a Golden Visa or free zone company visa. Your net worth is concentrated in Bitcoin accumulated over several years. Your annual income as banks define it may be minimal — despite holding millions in Bitcoin. You maintained your position through the 2022 drawdown.
Also for Non-Observant Holders
If you value the structural features — no margin calls, no income documentation, no forced liquidation — the product works for you regardless of religious motivation. Sound Property serves every Bitcoin holder locked out of the conventional mortgage system.
Governance and Compliance
Sound Property operates as a Qualified Investor Fund within the Abu Dhabi Global Market, regulated by the Financial Services Regulatory Authority. The fund is managed by a Category 3C licensed fund manager with Islamic Financial Business permissions.
Sharia Supervisory Board
A minimum of three qualified scholars — at least one with prior Bitcoin or digital asset experience — review and approve the full product architecture before any co-owner capital is deployed. The fund does not launch without this approval.
Independent Valuations
Property is revalued by RICS-certified appraisers at every tranche buyout. Bitcoin is valued at the 30-day volume-weighted average price. Neither party controls the valuation process.
AML/KYC & Source of Funds
All co-owners undergo full verification in accordance with ADGM requirements. The 13 BTC minimum is verified through on-chain proof of holdings.
No Margin Calls. No Forced Liquidation.
This is a structural commitment, not a marketing promise. The partnership absorbs BTC volatility proportionally. If Bitcoin declines, your ownership share adjusts — you are never forced to sell or top up.
Frequently Asked Questions
What happens if Bitcoin drops significantly during my term?
Nothing changes operationally. You continue living in the home and paying rent on the fund's share. At each tranche buyout, both the property and Bitcoin are revalued at current market prices. If Bitcoin has fallen, the tranche payment in BTC terms is larger — but you can always choose to pay in cash instead. There is no margin call, no forced sale, and no penalty.
Can I pay off early?
The buyout schedule is agreed at inception, but early buyout may be possible by mutual agreement. This is a term-sheet item, not a unilateral right.
What if I want to sell the property before the term ends?
A sale during the musharaka term requires both parties' consent. Proceeds are split proportional to ownership at the time of sale. The mechanics are documented in the partnership agreement.
How is rent determined?
Rent is indexed to the RERA Rental Price Index for the specific postal vicinity and building class — the same index that governs landlord-tenant rent adjustments across Dubai. It is not linked to any interbank rate or monetary policy benchmark.
What are the fees?
The fund charges a 1.75% annual management fee on deployed capital and a 20% performance fee above a 6% preferred return (hard hurdle). There are no entry fees, exit fees, or hidden charges.
Is this really halal?
The product is designed to align with AAOIFI Standards No. 9 and No. 12 and will be reviewed by an independent Sharia Supervisory Board before launch. We do not use the word "halal" lightly — the SSB engagement is rigorous and the fund does not deploy capital until it is complete. We encourage you to review the structure with your own scholarly adviser.
