So caution when you go public with that kind of horsepower. 

The way you construct the building, how high it is elevated, what is in the lower levels, does it have flood mitigations like breakaway panels, etc. all will impact the eventual rate for the Flood Insurance in the National Flood Insurance Program (NFIP).  

There are programs up to 80%, 30 year fixed loans for ITIN and NPRA borrowers, but you're going to run higher rates. 

All units have been rented to low-income tenants receiving assistance through voucher programs, and I plan to stick with low-income tenants to help alleviate the low-income housing stock in Phoenix.

I'm familiarizing myself with SONYMA (state of NY mortgage agency) programs and I know they require that no other properties be owned simultaneously if you plan to utilize a SONYMA loan.

Since you aren't/shouldn't be posting your financial info on a public forum, you need to find yourself a good lender that will figure out your options for you.Good luck.

Still trying to learn...but i understand mortgages are public record, yet i cannot figure out where to find that information.I have called my county Assessor's Office and the lady literally laughed at me.... 

Is this data not public in Texas?

Not sure if that specific program still exists but it came about due to Covid-19.

They may have programs that use the income from the properties to qualify.
