I don't see how that cannot be a good Vacation Rental...Could sleep 6 to 8+ also has 3 car garage that can be turned into rec room with items tailored to my ideal customers or something.

While they have been ideal tenants, I absolutely need to raise rent- as I said, it is currently well below market value.

I want to make sure the cash flow is good before investing all of it.I looked into a HELOC and that is what I ideally wanted but found that banks are either not doing them or your credit has to be impeccable to qualify.  

I hear NOVA is a little crazy but would NE/SE DC or Silver Spring / PG County be an ideal location?

Just curious I know the Market is Ideal for Vacational/AIRBNB etc so I know its very possible but just wondering what some peoples success or more importantly their Failures were. 

Ideally someone who is experienced with Strip Centers, trying to get a specific type of tenant.

Hard to pinpoint an exact ideal number of homes without knowing your entire management strategy.

Ideally, when it is time for you to move to your next rental property, those tenants stay in this property and you are now renting to them without occupying the same property.  

I have been spending about 10 hours a day (7 days a week)and just learning and slowly getting better from my brain anuerism and a stroke I had a little over 6 years ago.  

In general though, if you're able to buy cash, do the rehab with cash (and avoid a "back seat driver" - IE the lender - during your rehab), that is ideal.
