I will certainly try to refinance it when it is completed, perhaps a portfolio credit union would be open to refinancing, if not, then I'd simply sell it.One caveat however, she owns the property free and clear.

Generally the same banks, credit unions, savings & loans, etc will all make commercial loans.

Except for small local banks and credit unions that keep skin in the game (portfolio loans), doesn't the bank want the loan to go through so they can flip it over to Wall Street for securitization?

Start calling around to local banks and credit unions.

I used Delta Credit Union but they will only give me a 10 year amortization and they will only give 75% loan to purchase price (plus cost of work) regardless of how long I've owned the property.Thanks in advance!

Can I go to local banks/credit unions/lenders for the loan on a SoloK property, or do I need to work with specific banks/lenders?

•I will rent out the units at $285 pm (lol yes African prices) so $ 1710 monthly rent.

I'd say that 25% is the prevailing number you should be thinking about but it won't take 5-10 calls to regional banks, credit unions, etc. to figure it out. 

He is a retired police officer with his money in his credit union collecting maybe 1%.

Talk to your local bank/credit union to see what type of financing you qualify for.
