I am a BP follower and a real estate investor as well.  

Well maybe you can't? 

Well I did it 15 times so I guess I would but I'm getting older and more tired these days, and property is more expensive, so I'm less inclined these days.

I just want to be able to rent my property out and have the option to enjoy it as a vacation home as well.

Both my tenants (first and second/current) have been there multiple years each, young couples where one is a doctor receiving a housing stipend and the other spouse earns a healthy income as well. 

I'm hoping to have my Mom relocate there as well since SF seems to have a great community for retirees.

We are on the Eastern shore of Maryland as well :) We run the local REI (Delmarva REI) and have meetups once a month in Salisbury MD.

In this episode it talks about rental arbitraging many units in apartments and then being awarded government contracts where you house a large amount of government employees  and the government pays you well over market rent.

Have not had a 'issue' selling in the past five years..I would say the additional development cost of an extra bedroom/bathroom are probably well worth it in the long run..Good luck. 

@Kevin McKittrick Well in my opinion an electrical upgrade should be paid for by the owner of the property.
