I know it sounds very complicated and a little intimidating, but that's what your qualified intermediary is for!

Michael- I would first start by speaking with a lender and see what type of loan and amount you qualify for.

Could someone more qualified answer what IRS guidelines apply?

The question here is since their is a loan for $300k and both of my parents are retired (the only income they have is 1 rental, pension and 401k), I don't believe they could qualify to carry a loan onto new properties. 

They're actually easier to qualify for because they look at the asset's performance.

Alternately someone with experience working with Investors within Florida would be very welcome.I'm looking in particular for someone to qualify tenant buyers for properties I have under contract.Many thanks

In five years, I have only had one person apply that did not qualify.

Part of pre-screening is weeding out people who are interested that do not qualify, due to credit score, income, etc.

Although not everyone can qualify for this type of loan here’s a small breakdown of what can get you ready for this type of funding:Strong FICO is preferable.

The biggest challenge with this approach though is most lenders will require you to have a tenant in the home paying you to rent for a set period of time, I think 3 months before they will qualify you for another mortgage.
