You've got to start by remembering that the requirements to completely defer all tax in a 1031 is to purchase at least as much as you sell and use all of the proceeds in the purchase or purchases.When you sell with owner financing you are actually creating two different proceeds that go into your exchange account - cash from the down payment from the buyer, and a note from the buy for the remainder. 

Then I sell the property to Tenant Buyers who give me $25,000 plus or minus down.

Wholetail (wholesale + retail): Sold to landlords, or home buyers who want to build sweat equity.

At 5 units you are looking at commercial loans so you won't be able to use your 1st home buyer credit so stick to 3-4.

Okay, how do you find out how many MLS listing homes a realtor has sold or helped a buyer purchase?

Is the agent you are referring to your buyer's agent, the seller's agent or the property manager?

As a buyer, would you require an inspection of such homes?

The most common term is 20 years, transferable to buyer during sale if the buyer qualifies and agrees, or can be paid off prior to the sale usually by seller.

I have paid 125% to the Tax Assessor Collector, because it has been less that one year, and the buyer at auction has not sent a response to my  request for cost.

The first is that I came across a few websites and YouTube videos that suggested in a quit claim deed a mortgage doesn't transfer from seller to buyer - is this true or false?
