Only banks/mortgage brokers will be able to help you determine what kind of loan you could get, and only YOU can determine what type of payment you can afford. The advice to save a large downpayment is sound. Consider also if what you pay in rent is higher or lower than a mort loan payment. My first house I was paying less a month mortgage than I had been paying rent. A very nice situation! but Life situation changed and the X got the house. So back to renting for awhile. Was finally able to buy again at the height of local market and Current house costs me about tripple what I was paying rent. For me, this is still well worth it. But I sure was able to save faster with low rent!
my tip: Have at least 10% downpayment, and try to have an additional 5% or more set aside at all times for "just in case" emergencies (in case you loose one of your jobs, in case the hot water tank blows at 2am on a Sunday etc), and also start saving for the non-emergency things that will need doing periodically in the future (roof, exterior paint, chimney sweep, appliance replacement, new sofa...). There are many benefits to owning, but it is costly.
