Can I get a mortgage after a chapter 13?

Yes... You have potential options if you had a Chapter 13 that was discharged. Contact a local mortgage broker in your area. Give them a full application, and they can review your options.

As Joe Metzler has answered, you need only check with a local mortgage broker in your area. However, I would add they should include being approved for doing FHA insured mortgage loans since that is the best and often only option if not a Veteran, unless you hold a lot of equity in current property (or have $$ for substantial down payment). If a Veteran than that can be a wonderful option. Even if you have hold substantial equity in the property (25% or more) your options are a much higher rate and cost then FHA. So even with mortgage insurance, the very low rate/cost of an FHA loan can make it appear to be a very good deal.
