After some browsing on the market you will likely find some homes of interest to you and you will need to know what is within your financial comfort level. I recommend speaking to a mortgage professional to help you examine your choices. There are mortgage calculators on the internet, and PCS can help, though there is a lot more to a mortgage than just the rate.
