I helped a Colonel in the army buy a home 3 years ago that fit this criteria and they recently sold for a nice profit.2) You can buy a small multi-family. 

I use Profit Realty, very happy with them .

Better to get the property done ASAP so you can get all your cash/profit out and do it again.

See what types of clientele these parks attract and decide if it's something you want to pursue. 

I've spoken to some people and found that $220/sqft is about min to build in this area, which meams i cant buy the house for its cirrent value of ~220k and wholesale for a profit. 

Make a profit   

Same thing for your partner on the difference between his sale % of 2.7 mil and the anticipated purchase of 1.65.If the profit is large enough this might be justified. 

I am in the process of selling my 1st piece of land and want to put profits into a account but I don't know which one will be more beneficial in the long run, Solo 401k vs Self Deferred IRA.

Remember that there are 4 different profit sources for any property and I want all 4 working for me.

I'm going to make a good profit, and I am so thrilled!
