That's what I am doing...Sounds like I am on the right track! 

This sounds like a terrible deal, but not much info in hand.

To me this sounds more like personal loan to a business.

sounds like scammers to me.. 

It sounds like you’re thoughtfully weighing your options about whether to buy a home now or wait, which is great!

Sounds like PM doesn't like to do anything for noise complaints.

This guy sounds like a character.

The biggest mistake new investors make is to walk a property, maybe explain in general terms what they want and then let the contractor come up with the SoW.For a bedroom this could be:- replace carpet- repair closet dooror- remove carpet- remove curtains, nails and screws- replace closet doors, entry door SKU#- replace window SKU#- refinish hardwood floors 144 sqft, clear/oil-based- prep and paint all woodwork- patch walls, texture, paint walls eggshell white clay, ceiling flat white- replace light fixture SKU#, replace lightswitch w decora/white, replace 3 outlets&covers- install blinds SKU#Obviously, the cost would be quite different.

Your app concept sounds promising!

I personally like multi-family properties as they have less capex (one roof to replace vs multiple) but that is just my style with investing.
