I'm actually willing to have feedback on the rent/buy decision so here's the financials if you're interested in this. It's a challenging decision.
30% of my gross income is $1000/month, which is the HUD affordability factor.
The places I am looking at are $130,000-$175,000, which will be ~$730-$950/month including mortgage, taxes, insurance, PMI, and HOA with a 10% downpayment at the loan rates I qualify for at the moment (of course they may go up a bit.) I am currently pre-approved for $220,000, which I wouldn't dream of spending.
I currently pay $600/month to share a 2-bedroom, but it goes up every 6 months ~$75 and is pretty sub-par housing (great roommate but moldy and 1972 everything.) There's no rent control in my state and most leases are month-to-month and you can be evicted no-cause at any time with 30 days notice even with a lease. It also can take months to find a place even if you have the means to pay. In my very mustachian neighborhood, comparable market-rate rents (with no more rent protection than I have) are ~$800-$1400 month, trending towards the higher end. Rents might not continue to do the death spiral upwards they are currently doing (particularly as they are building more housing stock finally that the recession is turning around) but even during the recession before housing was crazy undersupplied, I was paying $800/month, so what I am paying currently is less than market rate even if we had another dip in the housing market.
Here's what my monthly budget will look like if I buy a condo next summer (high end cost estimate), and my income stays the same:
$1000 PITI & HOA
$170 to 401k
$650 Expenses (I have that very broken out if you want it- I track everything and this includes monthly padding for all one-time expenses and includes my travel savings)

$160 to charity
$450 to Roth IRA
$200 to emergency & home repair fund
That would put me at 30% of income on my mortgage, 18% of income being saved for retirement, 5% of my income to charity. Not the most mustachian of savings rate, but any additional windfalls after the tax man takes his cut will go into retirement savings.
This doesn't include any prediction of windfalls from my contract jobs (unpredictable but for the past 5 years $3-11K/year), airbnb rentals, mortgage tax deduction, etc. This is only based on my full-time job income.
