Clearly you're versed in numbers and assessing alternatives so surely you'll identify the optimal path!

I have thought about if there was a way to make money partnering with homeowners who want to renovate before selling but don't have the cash.Definitely seems to be aimed at homeowners not investors.

I decided to discontinue zBuyer as at least in the current market conditions in my area 95% were bored seniors looking to get their home value( tried some long term nurture's however when it came time to sell the kids stepped in with a "family" agent) and the other 5% were move up seller/buyers that simply could not afford to move up.

The owner at the time spiraled into dimentia, and his son wanted a quick sell to help pay for his home care.

It's just about having the right team in place where you can identify them and get offers submitted quickly and solid contractors that can give you realistic quotes so your financial forecasts are accurate. 

If I were in Detroit starting out I would be buying $10,000 homes, fixing them to rental conditions, lease up and sell turnkey to investors on the coasts for $75-100k.

In my opinion, they are treating  houses in lower cost neighborhoods like medium to high end flips, but selling to investors, which I don't believe is a viable business model. 

I think some people sell their judgements to collection companies for a very small amount but I have never done that. 

I want to sell the White House to two acquaintances (husband and wife).

You can sell that property as the trust and buy as yourself or as a "disregarded LLC"(an LLC that you are the only member of and that also does not file it's own tax return.In a 1031 exchange, the taxpayer for the old property must be the tax payer for the new property.
