A bit overkill ( another words waste of time  )  3- 5 is all that is needed, Hey I hope you sell a million of them and life is great, All the best But how would you pick those 3-5 properties to pull comps for?

If you paid $950k and only get $1M after selling costs, don’t bother with the 1031.

You find distressed properties and sell the contracts to investors for a fee.Partnering: Partner with investors who have capital.

Sellers worried they won't be able to sell in time before their lender takes action. 

When he sells he doesn't finance 100% of the purchase.

@Felicia NituIn addition if you actually want to realize that value, you need to count another 5% for selling costs, and the taxes from the sale.Assuming a 20% capital gains tax, your total ROI on the above scenario would be about 12%, even with the numbers you were using. 

Put new tires, clean them up with 10k then sell them for 100k. 40+% on your money.

This is perfectly fine if you are going to be living there a long time, but I see people who use a home as a stepping stool home to a larger home in future and make it very customized to their liking but then when try and sell it, it does not appeal to the masses.

you can do all of this on market and sell "as-is", minus the agents commission, sharing closing etc.

I purchase the land from a local jeweler who I tracked down at his business and asked he was interested in selling.
