I recently got screwed by a local small bank, so don't assume a small bank is necessarily better. I recently purchased a foreclosed property for cash much lower than market price and titled it to an llc, and needed a commercial equity loan for 80% of market value, NOT of the purchase price (BRRR strategy). I called over 30 local lenders and only 3 said they offer that, all others said they use purchase price. I selected one of the three lenders and a week before closing the loan rep said 'sorry, you can only get 80% of PURCHASE price', in other words 30k less than agreed upon!! The rep had 6 weeks to learn the bank lending rules, but only did so when it was too late for me to have any other options. I needed the funds for another purchase. The manager admitted that the rep screwed up giving me incorrect info but essentially said take it or leave it. Unhappily, I closed on the loan, and have been talking with the other two lenders about future loans.
Talk about a lender ruining a relationship from the get go... At this point I have difficulty trusting local lenders. Thorough research and due diligence is not always a guarantee of a good outcome, all it takes is one loan rep who gives you the wrong info.
On a side note, I've had a very positive relationship with a big lender of Fannie Mae loans (7 loans so far and an 8th coming up soon), but this lender offers no commercial loans for llc's, thus I resorted to local lenders.
