The driveway is 'Y' shaped, very narrow from the street to the back, then both houses have their own parking area in the back.The issue he is having is the other homeowner is 'accidentally' leaving nails, screws, and other puncture problem items on the driveway with alarming regularity.

Whether you are investing for Cash flow, appreciation, looking for value add, or just tax benefits.I first build out my buy box, which the more narrow it is, the better (multi family, 3 units, in XYZ zip code, at this price point per sqft, build after XYZ year......). 

I usually search through listings to get an idea on cap rates to narrow down states or cities.

And investors simply are too narrow to buy if RTP doesn't strike.

Quote from @Connor Golden: David's book is a great start.I think it's important to narrow in on a market, then look for a solid Property Manager.

Narrow down your desired home (seems like you have that done already).2.

They're so many options and even when you get it narrowed down... there even more options to choose from to make it exactly what you want.   

I don’t think you can narrow down Cincinnati by zip codes and more have to focus on the area as some zip codes can have a variety of areas.  

You essentially have essentially cast a super wide net and are going to get a ton of sales responses, but what I gather from your post that what you really need is a mentor/like minded investor to help hone in on recognizing good deals, narrowing your focus and absolutely protecting your capital.   

Where open floor plan looks especially awkward is when the living room is already narrow from side to side and goes straight back into kitchen like a train car.
