If you ask me *REALLY* bad idea to buy right now. Wait at least 2 more years. Until then rent a nice place for HALF the cost and add the money saved to your downpayment amount and also reap interest on the 70k cash you have now.
If you buy now you’re going to get burned as we are definitely at the very top of the market and it has a long way to go down. You will lose your 70k and perhaps you will be upside down for a long time to come.
BTW, Zillow is so inaccurate it can be safely IGNORED for all practical purposes 😉
