And as far as what troubles you could run into, I would think permitting would be the biggest struggle (that's not speaking from experience, just what I've heard).

I draw plans, for moving walls, windows, etc. and we've used them for permits in the past.

http://digonline.org/At the beginning of meetings, deals are permitted to be offered to the members. 

I will not bid a penny more for this home due to the amount of work and permits that I will need to purchase.

We put in more than 200 hours of our own labor, hired out a contractor for the things that required license, permits or inspections and ended up with a total rehab of $12,000.  

It qualifies as a residential purchase and may permit some of you to have your own place or even rent out a unit or two. 

This is the series of events thus far....we needed an occupancy permit from the city.

The Treasury Regulations are very clear that a Qualified Intermediary is not permitted to release the 1031 Exchange funds unless certain events have occurred such as the 45 calendar day identification period passing or the 180 calendar day exchange period passing.

I'd also check with PD- he's required to register his address, to confirm if being around kids is permitted.

@Robert SlatkinThe permitting part is the most painful part, sometimes it might even take longer than the rehab itself.
