This was in a wide range of price homes including 2M+We decided not to build after doing some research and noticing the industry hadn't gotten any better, even though we felt we could get more bang for our buck.

For a couple/few hundred bucks a month, I think it's worth it.

New into wholesaling, looking for good leads in the Jax fl area starting driving for bucks in the morning!

Do those guys ever try convincing investors that there's big bucks to be made in port-a-johnnies and the investor will never have to smell poop?

Don't guess.Run your numbers using the rental property calculator.Mortgage rate if you use Colin Powers in red bank is 3.875 but may cost you a few bucks to lock in about 1-2k or assume 4.0 with no cost.plug in taxes,  estimate repairs, estimated homenowner insurance (call an agent if you dont know it), water (call water company) if you intend on paying for it, projected rent etc.  

Otherwise, I'd probably say there are closer places to make a buck.

I would not spend a thousand bucks to try to save a 17-year old unit. 

I have added the property managment fees into my calcs and could cashflow 200 bucks while living there (25% vacancy).

I just started to practice analyzing deals ( used up the free 5 trials for rental calculator, so basically made an excel using old youtube videos on the 4 block technique figuring out CoCROI. )  What i've realized for my area ( Houston, TX) is basically anything over 130k basically produces 0 or negative CoCROI because ultimately your rent is the total income you get and subtract expenses(which usually adds up to around 700-800 bucks be conservative) and your mortgage(which would be around 500-600 bucks a month for a 100k-130k loan)most of the homes near Houston average (base on craigslist, rentometer, realtor.com) 1300-1600 on rent for a traditional 3/2 SFH.

Don't try to buck the system, it's not worth it.
