Hollow sounding floors sometimes mean it's cracked or there is a recess under it.

I really like the blue 3M masking tape, and the green Frog Tape (or similar from other manufacturers) works pretty well. 

TELLING YOU, the serious flippers don't give a frog how much you are making.

If you want more of the country feel check out north Hendersonville along Long Hollow Pike area.  

Then re-install the door.If it is an interior door, one of those cheap hollow ones, you can remove the door and drill new holes for the screws in the frame.

keep cash flowing, there's no rush your doing good no need to play leap frog when your plan is working, before you know it you will be right where you want to be and without taking heavy risks

You have to kiss A LOT of frogs using this as there are some properties that are insanely overpriced for the amount of work they require.If you are looking to flip, this is not going to be a good method.

Park Cities, Preston Hollow or Lakewood?

This particular unit is pretty trashed- there are holes in the hollow core doors, baseboard radiators are beat up, counter tops are chipped, carpets are snagged and stained, screens are damaged or missing, and the entry way is in dire need of some love.  

House hacking leap frog style.
