Are you putting at least 20% down and borrowing less than the conforming limit (510K)? That should get you the best terms / lowest cost, and I don’t know why any lender would care that it’s a 4-plex. Fannie/Freddie back these loans and make the rules.
I haven’t looked at the latest guides or done this myself, but from past experience (of searching and comparing mortgage rates and costs) both require 25% for investment property. But a 4-plex that will be your primary residence is supposed to fall under the same rules as a SFH, so 20% for the best terms. You can find the underwriting rules on their websites.
I’m mentioning it just in case lenders are steering you into the wrong product (or, worse, don’t know the difference).
I appreciate it, a 4-plex w/ primary under Fannie requires 25% LTV, but Freddie requires 20% so just need to make sure the lender is aware and checks the guidelines. Almost all the lenders on zillow changed the rates (SFH) on me when I mentioned it was a 4-plex regardless if it was primary and 20% or 25% down. Anyway I think I got financing squared away, I wish the property cash flowed better but it’s definitely a sellers market.
