What this calculator does
The Washington DC rent vs buy calculator compares the true cost of owning with the cost of renting over the number of years you expect to stay. It counts the costs that never come back — interest, property tax, insurance, upkeep, HOA or condo fees, and the cost of buying and selling — and credits the owner with the equity built. For renters, it credits the investment growth on the down payment they did not spend.
DC housing ranges from rowhouses in Capitol Hill, Petworth and Shaw to condos in Navy Yard and NoMa. Many workers compare DC against suburbs in Montgomery and Prince George's counties in Maryland and Arlington and Alexandria in Virginia.
How to use it
- Enter a realistic home price and the rent for a comparable place.
- Set your down payment, mortgage rate and how long you plan to stay.
- Keep or change the local defaults: property tax (0.72% of value is Rate and Reason's rough Washington DC starting point), insurance, maintenance and HOA dues.
- Adjust rent growth, home price growth and investment return — these assumptions move the answer most.
- Read the break-even year to see how long you would need to stay for buying to win.
The formula
Net cost of buying = buyer closing costs + mortgage payments + property tax + insurance + maintenance + HOA − (sale price − remaining loan − selling costs − seller transfer taxes). Net cost of renting = total rent − investment growth on the down payment and closing costs. The cheaper option is the one with the lower net cost.
Worked example for Washington DC
Default Washington DC inputs with a 7-year stay:
| Item | Amount |
|---|---|
| Everything paid as an owner (down payment, closing, mortgage, tax, insurance, upkeep, HOA) | $564,945 |
| Equity you walk away with after selling | -$269,697 |
| Seller transfer taxes on the future sale (included above) | $11,592 |
| Net cost of buying | $295,249 |
| Rent paid | $303,434 |
| Investment growth on the down payment you did not spend | -$59,538 |
| Net cost of renting | $243,895 |
Over 7 years, renting comes out ahead by $51,353. Buying starts to win after about 12 years with these assumptions.
What tips the balance in Washington DC
DC taxes owner-occupied homes at $0.85 per $100 of assessed value after a homestead deduction, and limits yearly assessment increases for homesteads to 10%. That makes DC's effective residential rate lower than most of the other cities here.
DC charges a recordation tax, customarily paid by the buyer, and a transfer tax, customarily paid by the seller — each 1.1% under $400,000 and 1.45% at $400,000 and above. Qualifying first-time homebuyers can use a reduced 0.725% recordation rate.
Common mistakes and tips
- Comparing rent with the mortgage payment alone, ignoring tax, insurance, upkeep and transaction costs.
- Assuming fast home price growth — try 0% or 1% to see the downside.
- Staying a short time: transaction costs usually make buying expensive for stays under about five years.
- Forgetting that a renter's savings only help if they are actually invested.
- Using a statewide property tax rate instead of the local one — Washington DC has its own rules, covered in the Washington DC property tax calculator.
Frequently asked questions
Is it better to rent or buy in Washington DC?
It depends on how long you stay and what you assume about prices and rents. With this calculator's default Washington DC inputs, renting comes out ahead by $51,353 over 7 years. Buying starts to win after about 12 years with these assumptions.
How long do I need to stay for buying to make sense?
Look at the break-even year in the result. It is the first year when the net cost of buying drops below renting with your assumptions.
Why include investment returns for renters?
Money not spent on a down payment and closing costs can be invested. Leaving that out makes renting look worse than it is.
Are Washington DC transfer taxes included?
Yes. The seller-side transfer taxes on the future sale come from the Washington DC rules in the site's tax engine, and buyer closing costs are an input you can change.
