Legal documents and customs are tricky in a native language let alone a foreign one.

The cost of labor and materials now is insane.The type of work on my custom house is about 400 a foot.

Reach out to someone like @Dave Foster to avoid making a costly mistake. 

Quote from @Dave Foster: @Bryan S., I always found that the steepest part of my learning curve as I transitioned from SFR to STR to Commercial land development and MF (all using 1031 exchanges) was learning what "didn't translate" from the prior type. 

there is a ton to being a GP syndicator raising 3 to 5 mil 50k at a time.. you now have 100 partners and the amount of oversight  customer care and Risk in my mind has to be considered compared to what you do now which is build sell and make nice bucks without being beholding to anyone but your construction lender. ??

If you want to run a charity by all means run a charity but don't speak such insanity that letting customers STEAL is ok, it's not.

(IRC section 121(d))@Dave Foster might have more to add here. ...

I focus a huge amount of time on tenant screening and providing exceptional property management/customer service.

An AC unit in beaucoup Hot weather may have an up charge from the installer because he knows he can get it from customers who want immediate cooling.

Personally, I find that buying is usually quicker and cheaper upfront, while building offers customization but requires more time and coordination.
