buy my house

The house we are currently renting is adorable. Its a tiny place with not much space but for me and the hubby it would be just great. I mean the kids are all going to be gone within the next five years so why do i want to rattle around in some monstrosity and try to keep up after it? The house we live in now is 2 bedrooms and 1 bath which is admittedly too small for all 5 of us at the moment but like i said in 5 years will be great for just me and the hubby. The plan is to buy the house and add a 3rd bedroom and a bathroom on the backside where the porch is. We dont use it anyway and could really use the extra bedroom. Once the kids are moved out the Front Bedroom would become the Library with a reading nook and lots of books. The Second Bedroom would be the home office. Also I am studying Feng Shui at the moment and unfortunately the “Love Center” of my house is out on the back porch. How depresing. So the back porch would become the Master Bedroom. the only problem with this idea is that its going to cost abut $11,000.00 to do what we want to with it. Oh and we have to buy it from our landlord first. Sigh
