How much can i get for my house?

You need to call a real estate agent to come out and do a market appraisal. The sale price will be based on size of home, neighborhood, # of baths, bedrooms, etc., but most importantly, what have similar houses sold for in your neighborhood in the last 6 months to a year and what does the market look like now in your area. For example, depending on where you live, the house you describe could go for between $75,000 and $1 million (your definition of "huge" could be small to someone else.)
