I am a Private Investor or Hard Money Lender.

I'll address your second paragraph with where you are talking about a 10+ unit building. 20% has historically been a minimum down payment (I'm saying minimum...it might be more down from lender to lender) on commercial property.

Rabbu is also solid, but the standard for lenders is AirDNA.

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Your Lender My suggestion to find #2 & #4 would be to go to the top of this page and click on FIND AN AGENT & FIND A LENDER.

That’s probably best way as a lender to keep title in your name but in many states you still may need to foreclose on the cfd - What state is this in (please don’t say DC)

Some lenders use that to udnerwrite which shows the quality of the projections. 

Following David Green's Core 4 strategy (realtor, contractor, property manager, and lender) gives confidence to invest anywhere.

It's a great place to network and meet agents, lenders, wholesalers, attorneys, etc.

I have a high credit score, good income, and money in the bank, but I have been having a difficult time finding a DSCR lender I feel like I can trust.
