In my opinion, $1k additional per unit totaling $3k is rather low considering the additional liability the Architect will incur. 

I have seen multiple properties in Puerto Rico that I am interested in due to low cost.

I had started low.

The work you mentioned is absolutely negligible and you will open a real pandora's box bringing inspectors into your home and start an endless stream of trouble.

Otherwise, you can get a conventional loan as low as 3% down, but 5% is easy to get with decent credit.If you are in a position where you won't qualify for FHA or owner occupy, I would recommend looking into private money loans.

I made a low ball (i thought) cash offer.

I have the money for repairs but would like to get into the property with no or low money down.

We were all set to close on the sale of my flip until my buyers lender decided they needed a few more conditions cleared: It is a high interest (8%) jumbo loan with 10% and low 600 credit (640 maybe?).  

At this point in time all the properties, unless they are of a very low value, are most likely a liability having negative cash flow. 

I get the benefit for me, but our market is extremely good now and rents are sky rocketing and vacancies are extremely low, so if I were to try to do a master lease for cash flow, why would a property owner do this?
