Basically, if you find a property where you can charge rent to cover the mortgage, the lender will count that potential income as YOUR income and will help you get your loan.

I remember he was just standing against a wall by himself, just watching and listening.

I am wondering if I would be better off tearing down a wall to make three bedrooms instead of four.

A house looks good from a photo,but what inside the walls,the foundation,pluming,the area and marketability.

Checked basement walls for leaks/cracks, looked at the roof, etc.

All units have the same kitchens: Pass through / Galley with ~7 ft of wall on each side.

It's cheap ($2 per tube).Another thing you can do is put foam gaskets behind your receptacle and switch plate covers on all exterior walls - this will reduce the draught and heat loss through the hole into the wall cavity. 

Our thoughts are to finish the full basement and add a bathroom there, knock out the wall leading to the kitchen to insert a breakfast bar, replace carpeting, repaint, and take off the siding and replace with brick or granite for an exquisite finish.

Anyways, there was coffee stains (and more) all over the walls and furniture.

A wall separated the bathroom from a 140 square foot laundry room.
