@Angelina Essuman That is a great question. I wish I had a better written out response for that but here is my stab at it.
Do you lend directly to an LLC?
Some lenders will lend directly to an entity if you add in a personal guarantee. Others will not lend to an entity at all. See what is possible.
Do you allow transfer of deed from a personal name to and LLC?
You will want to make sure you can hold your rentals in an LLC. Liability protection is key!
Do you offer refi/consolidation of loans?
This isn't key until you have 5+ rentals. Then you will want to start thinking about packaging loans in to bundles that will be held with one commercial note. I am not a long term lender but I believe Fannie Mae limits the number of loans an individual can have to 10 (this would include a primary residence). This is just for conventional government backed loans. There is no limit to private mortgages.
I know there are tons more great questions to ask and I hope that some more qualified long-term lenders can come along and offer their advice.
