@Kyle Carter People hit on the obvious, hype and excitement of a large name company like apple moving to an area. 

Unkempt lawns, trashy or broken down vehicles, mattresses and trash on empty lots, boarded up houses, bars on windows, dealers and hookers on the corners, the lack of stores or gas stations, occupied properties are dilapidated, etc.Or when Google maps shows stuff like this:

If you're more of a 'personal referral' person than a 'do research online' person, and this is local to you in Manhattan, KS, hit up one or two of the trades people in the "little apple all stars" BNI group.

I would say as an agent if a property is in a rough area I don't put signs since it can attract those bad apples or get stolen. 

@Brandon Croucier is giving you solid info on finding an experienced and honest mortgage broker who can shop your exact scenario both ways, with the rehab and without and break down the benefits of each with all fees so you can see an apples to apples comparison. 

I like the way you are thinking, but it's a little apple before the cart although you seem to get that you need experienced partners to make this work.

Every adult should be fully screened to ensure you aren't renting to a violent criminal, drug dealer, etc.

I guess we just picked a foul apple... 

Technically it would be best to get a C Corporate or S Corp. to flip properties and since you are considered a dealer if you do several properties a year and this could have negative tax consequences in an LLC.

My friend all it takes is a bad apple. if you are asking, you are lucky you have not gone through a bad experience-Evicion.
