We were receiving $2800 and mortgage was $3250. 

The problem I am having is finding investor friendly lenders within my country.

RE  Mortgage banker etc.2. criminal and credit back ground checks with redacted personal info IE SSI. but you want them to know your not an ex felon or did not pay your child support etc.3.

I’m also a Private Lender and often times, fund these builds.  

I just bought a property to flip with a Hard money lender, and started working on it and supposed to sell in 6 months.

With a pool of mortgages, or an investment in a series LLC, what is it that I actually own?

Pay the mortgage.

Aggressively pay off the mortgage and save a lot of money on interest.

all paid for with cash.no credit cards. no school loans owed. when we shopped around for rates on a mortgage in May, 1 broker said to me twice, "you mean you really have no debt except for your mortgages?"

However, the money I’d save by not paying $3500/month mortgage is $42,000 after 12 months – thus recovering the money paid on the capital gains tax.QUESTION: would you advise selling the rental to pay off the new home and take the $1400/month rental income loss (and gain $3500/month savings) or would you advise keeping the rental?
