Investment Property Loans in Washington, D.C.

A D.C. short-term rental must be at the host's primary residence, which the code defines as a property eligible for the homestead deduction, and needs a basic business license with a short-term rental endorsement.

For investors: A rowhouse or condo bought as a pure rental cannot be licensed for transient guests at all. Condo, co-op and HOA units also need proof that the association allows short-term rentals before the licensing department will issue the endorsement.

D.C. caps vacation rentals, where the host is away and guests have the whole home, at 90 nights per calendar year, and booking platforms may not accept nights past that cap.

For investors: Exemptions cover only hosts sent outside D.C. by an employer for over 90 days, or away over 90 days for serious medical treatment of their own or a family member's. Stays with the host present fall outside the cap, so a suite in your own home is treated differently.

D.C. issues one short-term rental endorsement per host, valid two years, only to a natural person, and hosts must carry at least $500,000 of liability insurance, which the booking service may supply.

For investors: Because the host must be a natural person living in a homestead-eligible home, a property bought purely as a rental, whether held personally or in an LLC, cannot earn nightly income. One endorsement does cover several spaces on one property, such as a bedroom and an in-law suite.

Every D.C. housing provider must register each unit in DHCD's RentRegistry as rent-controlled or exempt, and any unit left unregistered is treated as rent-controlled.

For investors: File the claim of exemption soon after closing. The small-landlord exemption covers units owned by a natural person, not a corporation, holding four or fewer D.C. rentals, so vesting in an LLC can forfeit it, while buildings put up after 1975 stay exempt either way.

D.C. property left unoccupied for 90 days or more must be registered with the Department of Buildings as vacant or blighted, with fines of $1,000, $2,500 and $5,000 a year for failing to register.

For investors: A gut rehab between tenants can land the property in the vacant class taxed at $5.00 per $100. Active construction with permits from the last 12 months can earn a limited exemption, but exemptions are reviewed yearly and cap at five years in any 12.

D.C. Class 1B covers residential property with no more than two dwelling units: the first $2.558 million of assessed value pays $0.85 per $100 and anything above pays $1.00.

For investors: The higher slice applies only to one- and two-unit homes, so a three-unit or larger building stays at the flat Class 1A rate of $0.85 at any value. Only the value above $2.558 million pays the higher rate, not the whole assessment.

DC Water bills monthly for water, sewer, metering, a water system replacement fee and the Clean Rivers Impervious Area Charge, a sewer fee based on a property's roofs and paving.

For investors: The impervious area charge follows the lot, not water use, so it keeps billing while a unit sits empty. The board votes on rates each July and they take effect with October billing, the month to update a hold's expense line.

D.C. faces riverine, stormwater and tidal flooding; DOEE lists recent stormwater floods in Bloomingdale and LeDroit Park in 2012, Cleveland Park in 2016 and Rhode Island Avenue NE in 2023.

For investors: Interior stormwater flooding can reach basements far from the rivers, so check the District's new stormwater flood maps for any English-basement rental. DOEE's FloodSmart Homes program sends a professional for a free flood resilience assessment of the building.

D.C.'s Chief Financial Officer reported in September 2026 that federal workforce downsizing since January 2025 cut District employment, with metro-area jobs down 2.6% year over year in the second quarter of 2026.

For investors: The same letter shows residential property tax liability up about 3% while office tax liability fell, and home sales slowing less sharply than other transfers. Underwrite rent growth and vacancy conservatively for units that lean on federal workers.
