How many investment properties do they personally own?

I personally like SFH, but thats just me. 

Personally, I prioritize land lord friendly states because this significantly reduces risks.

And just to clarify if anyone else is reading this: buying an interest rate cap, while effectively buying down the interest rate is NOT like buying down the rate on your personal mortgage.A point on your personal mortgage locks in the lower rate for 30 yrs and the mortgage fully amortizes.  

my buyers on my new builds even get sewer scopes I personally would never buy a home without one..  

I would personally not recommend Batch.

The lenders we have spoken to will only finance as a personal residence.

There are schools all over, including Wilmington for sure. https://dpr.delaware.gov/ has all the details on schools and requirements, typically the schooling can be done online and then the test is done in person at a testing center. 

B is going through an eviction) The realtor said the main issue is whoever did the initial renovations cut a lot of corners and it shows when you go to the property, it looks perfect in pictures but in person not so much.

Personally, I've been investing more than 50 years and never looked at the demographics for a neighborhood one time because I always felt that you need more personal knowledge about the neighborhood e.g. whether it is blue-collar working people, whether it infested with gangbangers, what the ability to increase rents is, etc. and the only way to get a good feeling and understanding is to personally visit the neighborhoods in the daytime, evenings and on weekends because weekends and nighttime is when the bad people come out like cockroaches.
