It took a bit longer and cost a bit more than we expected but in the end I think you'll agree it turned out great.

Sure, there were little things that I missed at first (code issues, mostly), but those are things you learn as you go along, and that don't generally cost a whole lot to fix even if you do miss them.Even after 60+ rehabs, I still bring in structural engineers, foundation specialists, termite inspectors, mold guys, etc., when I spot signs of potentially large issues, but the other stuff I can evaluate myself because I do exactly what my inspector used to do during his inspections (at first, I actually used his inspection checklist to do my walk-throughs).Over the next few months, I'm planning to get to work on some software ad videos on inspecting, evaluating, estimating, renovating, etc.

"Set it and forget it" has cost a lot of investors a lot of money!

It can cost a fortune to cap all the old trim with trim coil. 

In reality, all those repairs _could_ cost a very small amount depending on if those furnaces are really shot or if you can find used furnaces or if you can get by with blanking off some of the circuits that don't work, etc. 

If you want a PM to hire a GC, it might not be worth it, the PM will not have enough time to understand your needs, but if you want only to only manage from start to finish, it will cost a bunch, that fee is more useful if you add it and hire a more competent and reliable GC, a light commercial GC or custom build GC will be of your best interest.

I learned the hard way by doing and making a lot of mistakes that cost a lot of money but I learned fast and grew my first building company from $0-$30 million in seven years then sold it. 

Also if a major expense such as a roof needs to be replaced the HOA can raise your monthly cost. A

@Jeff Costa great question!

@Adam Steinberger - Plenty of options out their...lawyers cost a bunch but if you've done your research about the firm and their reputation I would suggest eating the expense to fully learn about your options.
