Selling a Condo: Estoppel Letters, Special Assessments and Rental Caps
What is different about selling a condo: the estoppel certificate, pending special assessments, lender rules that shrink the buyer pool, and rental caps.
Updated September 2026
A condo sale has a third party in it that a house sale does not: the association. It holds documents the buyer needs, it can owe or be owed money that changes your proceeds, and its finances decide whether a buyer can get a loan at all. Most delayed condo closings are delayed by the association, not by the buyer or the seller.
The estoppel certificate
Before closing, the title company asks the association for an estoppel letter (some states call it a resale certificate or a status letter). It states what you owe the association, what assessments are pending, whether there are violations against the unit, and what transfer fees apply. Associations take days to weeks to produce it and charge for it, and the closing cannot happen without it. Order it the day you go under contract. If the association is self-managed and the treasurer is on holiday, that is your closing date moving.
Special assessments
An assessment that has been approved but not yet billed is the single biggest surprise in condo sales. Who pays it is negotiable and depends on the contract and on state law, but a buyer who discovers a large pending assessment for a roof or a garage after signing will either walk or reprice. Find out before you list whether anything is approved, proposed or under study, and disclose it. In older buildings, ask specifically about structural inspections and reserve studies, because several states now require them and the resulting assessments can be large.
Financing: the part that shrinks your buyer pool
A buyer's lender does not only underwrite the buyer, it underwrites the building. Conventional and FHA loans have rules about the share of units that are owner-occupied, the share owned by any single investor, how much of the budget goes to reserves, whether there is pending litigation, and whether the association has adequate insurance. A building that fails those tests cannot be bought with a normal mortgage, which removes most buyers overnight.
Ask the association whether the building is currently approved for FHA loans and whether any lender has recently declined a unit. If the answer is bad, you are selling to cash buyers and investors whether you planned to or not, and pricing for a retail buyer who cannot get a loan wastes months.
Rental caps and investor buyers
Many associations cap the number of units that can be rented, require an owner to live in a unit for a year or two before renting it, or ban short-term rentals outright. A cap that has been reached means an investor cannot rent your unit after buying it, so investors will not buy it. Check the current rental count against the cap before you decide who your buyer is. If the cap has room, say so in the listing; if it does not, an owner-occupier is your market.
Right of first refusal and approval
Some associations, and most co-ops, have the right to approve the buyer or to buy the unit themselves at the agreed price. Approval takes time, adds an application and a fee, and in a co-op can end the sale. Get the process and its timeline from the manager before you accept an offer, and write it into the contract so nobody is surprised.
What to gather before listing
- The declaration, bylaws and current rules.
- The last two years of budgets and the most recent reserve study.
- Minutes from the last year of board meetings, which is where assessments and litigation show up first.
- The master insurance certificate and what it does not cover, so a buyer knows what their own policy needs.
- Your own account statement showing dues paid to date.
What you owe at closing
Beyond ordinary selling costs, expect the estoppel fee, a transfer or move-out fee, sometimes a capital contribution, prorated dues to the closing date, and any unpaid assessment the contract puts on you. These add up, and they are easy to forget when planning around the sale price.
When a cash sale makes sense for a condo
When the building fails lender rules, when a large assessment is pending, when litigation is open, or when the unit has a tenant and the association makes showings hard. In every one of those cases the financed buyer pool is small or empty and the delay belongs to somebody else. A cash buyer used to condos will still want the estoppel and the documents, but does not need the building to satisfy a lender, and can absorb an assessment into the price rather than reopening the deal over it.
