there is no better strategy. 

I really like to keep a close watch on my investments and living within access to them is the best way to insure the property performs to my standards. 

No one is gonna pay her more than its worth, much less appraise for.

They have almost no reviews.With 6-7 residents, how often should I expect to need repairs? 

If not there are alternative ways to qualify with no FICO.

I put a lot of time and effort into finding a new tenant, and there is no gap between the two tenants.Can I still charge the penalty of two months' rent as stated in the lease?

NO kidding way over thought and over kill.. a landlord with proper insurance and takes care of their property ( not a slum lord) has extremely low liability issues.. disputes with tenants is generally over deposits and when you go to evict them..

Attached single-family rentals are especially promising due to lower maintenance costs and higher rental yields.But now think of the families who wouldn't want to live in such conditions, I think there is a future, because demand is no where to be finishing

@Matt Bertsch no experience with Buildium.

I was able to take out money with a 4% fee up front and no interest for one year.
