Hello Eugene -
Just a thought, have you gone through your finances to see what price range or monthly payment you can afford for a home? And, remember to add something for HOA fees, if a condo, property taxes, programmed and general maintenance and repairs, insurance. If you find a home that, on the surface, looks like you will have the same monthly payment, or even a tad less than the rent you are paying now, you need to stop and review things.
100% financing will mean that you actually have no financial stake in the house itself, when you buy. Yes, you will have other costs and expenses to make the deal work, but it's really very risky to do it this way, and is part of the reason our housing market is in the mess it is today. If you would need to buy with no cash down, it might be a thought to continue leasing for a year while, as you build up financial reserves.
Home ownership is truly a wonderful thing - and when it comes with manageable finances and monthly out go, it's even definitely worth it.
