Have you taken a look at the NYT rent vs. buy calculator? It's a few years old but most of the variables are adjustable so you can make it relevant.
https://www.nytimes.com/interactive/2014/upshot/buy-rent-calculator.htmlWe live in the Mid-Atlantic, in a mixed rural/suburban area. In our area, home prices and rents have been rising with no end in sight (and I would assume most of the country is tracking the same).
Our current residence, for example: in 2016, its estimated market value was $170k and as of today it's estimated at $190k. We rent, and when we moved in we were paying just a hair under $1200 a month. (3Br, 2.5Ba, 2k sq. ft. townhome w/garage and finished basement). We're now a hair over $1200. Our neighbors next door, whose house has a mirror layout to ours and is owned by our landlord as well recently moved out. Our new neighbor now pays over $1400 a month, in a house with lower quality finishes and less yard. We estimate if we were to move today, ours would be listed for $1475+.
Another example: we were considering buying a home a couple years ago, and the median home price in our target neighborhood at the time was just under $200k. Currently the median home price is approx. $220k and expected to kiss $230k by year's end. For reference, in 2014, the median home price in this neighborhood was $180k.
In short - we're going to sit the "buy" market out for a bit until it deflates.
