What percentage of the sales price one would expect a seller to typically accept?

The 1031 starts with the closing of their sale. 

A relative of mine listed his home for sale "as is". 

I was thinking about structuring a deal as follows:he owes the 1st mortgage $211kI was going to go in and give him $5k entry fee at the sale price of $235k.I need about 5-6 months to rehab the property, list it, and sell it off for the projected 375k.any guidance on how to structure this would be highly appreciated as I want to make sure that when this property sells he is only entitled to the $235k price, which $211 will be going to the mortgage pay off and remaining in his/and his future ex wife pocket. 

I have worked with her in the past and she will be a great asset to your team.Regarding your interest in conventional loans to include vacation home loans, DSCR, etc, I have helped quite a few investors with the same products. 

Hi @Eddy Wehbe, brokers are doing the work that you don't want and, in a lot of cases, can't do (think of connecting you to branches that understand and are able to help investors, providing mortgage products that normally wouldn't be offered, getting rates that direct banks are not giving).

If that happens, I'd of wished I'd just paid the tax at the time of sale vs. 1031 it somewhere else.    

As long as the investment portion of the 4 plex is equal to the net sales price of your rental you can use the other unit however you want. 

So, I found a multiunit house and a single-family house both attached to each other, both owned by a church that put them up for sale. all units are already rented but lower than the market value.

There also may be a deed restriction preventing you from reselling for a period of time, but those are usually for short sales.
