I am ready to jump in and have looked a quit a few properties for a multifamily purchase. I just haven't jumped the gun in discussing finances.
How do you vet the best? Do you just use an online site to get preapproved or do you use a specific lender?
I would advise against an online lender because they are not as customer-focused and in my experience have a higher chance of not closing on the loan. Hopefully, you can get the names of specific lenders from others on BP but if not reach out to your bank or credit union as well as small, regional banks. Ask your agent as well, any good agent will be able to give you a list of great lenders.
Personally, i have two lenders that refer to all my clients because they have worked well with me in the past. However, I also suggest speaking with any banks you do business/have accounts with. At the end of the day, rates and fees should be pretty similar, so customer service and support are key.
