There are U.S. lenders that finance Brazilian buyers in Key Biscayne with no local credit history. What decides the deal is which Brazilian documents they accept and in what format they want them.
A lender that cannot pull an U.S. score asks for equivalent proof from the home country: the Brazilian income tax return, proof of earnings, statements from Brazilian banks and, almost always, a bank reference letter. What is particular to the Brazilian buyer is that Brazil requires residents to declare assets held abroad to its own authorities, so the financed unit in Key Biscayne will appear in two separate files: the lender's and the Brazilian declaration. Making the amount, the date and the named owner agree in both is something to settle before signing, with an accountant in Brazil, not when the filing deadline arrives.
Key Biscayne moves through a different channel because the village keeps its own permit counter and because everything that reaches the island crosses a single bridge. For a buyer abroad that is not scenery, it is logistics. The contractor quoting a renovation prices in travel and the delivery window in which material can be unloaded; the appraiser and the inspector your lender sends depend on that same bridge; and scheduled work can stop because of a closure nobody told the buyer about. On top of that, the county does not grant the approval: height, setback, landscaping and dune protection rules are set by the village, and when the parcel touches the shore a state authority enters as well, so a wall, a dock or a pool may require more than one file. Ask your insurance broker how the carrier reads the exposure of that specific parcel and what it requires before issuing; ask your closing attorney whether dune restrictions or easements are recorded on title; ask the village which work is approved at the counter and which goes before a board. It also pays to learn who manages the building or the association, because on a small island the manager is the person who actually answers.
What is specific to Key Biscayne
A barrier island with its own village government, reached only by the Rickenbacker Causeway, with large parks at both ends. Oceanfront towers, low-rise buildings and a core of single-family homes inland. A single tolled road in; there is no rail and no alternative if the causeway closes.
- what the single road implies: evacuation, rush hour and closures for works or events
- the parcel's coastal exposure and what that means for insurance
- the village's own rules, which are not the county's
What to verify, step by step
- Ask each lender whether it runs a foreign-national programme without local credit history, and request the full document list in writing.
- Confirm whether it accepts the Brazilian income tax return and supporting documents in Portuguese, or requires sworn translation.
- Ask which identification it accepts from a Brazilian buyer and at which stage of the file it is needed.
- Ask the lender for the bank reference letter template it accepts and take that to your bank in Brazil, instead of sending the standard letter.
- Ask an accountant in Brazil which details of the transaction are needed for the declaration of assets held abroad, and request those same details in writing from the lender.
- Confirm that the Key Biscayne building you are interested in is financeable for that lender before making an offer.
Mistakes that cost money
- Forgetting that the financed unit also enters the declaration of assets held abroad before the Brazilian authorities, and learning this after the deadline has passed.
- Sending Brazilian statements without asking how many months the lender wants or in what format, and then repeating the whole exercise.
- Searching for an unit before knowing whether there is financing and of what size.
Frequently asked questions
- Can a Brazilian bank finance the purchase in Key Biscayne?
- Lending secured on a Florida property is usually done by an U.S. lender. If your bank in Brazil offers some alternative, ask it directly and request the terms in writing.
- Does the lender ask for the declaration of assets held abroad?
- No: that is an obligation towards the Brazilian authorities, separate from the lender's file. What must be declared and when is a question for an accountant in Brazil.
- Can you buy in cash and finance later?
- Some buyers do. The terms are set by each lender, so it is worth asking before closing rather than after.
