It's a big move to buy a house, but it's also a good investment. My thoughts are to stick to a mortgage with a payment you could afford even in a bad month. That may mean buying a smaller house, but in the end you will suffer less paying for it.
And making your payments weekly or twice a month will signifiicantly reduce the time it takes to pay it off.
And doesn't every codie have a spare bedroom and an apartment in the basement?
