If you're moving out of the area -- or you've simply outgrown your current home -- you might assume the next step is to sell your home. But if you've got a super low mortgage interest rate (say, 3% or less), it's worth pausing for a moment.

We might never see mortgage interest rates that low again... possibly ever.  Mortgage rates today are much higher (6% +) so if you sell and buy something else, your monthly payment could increase a lot -- even if the new house isn't much more expensive.

Here's the good news: you might not have to give up that low rate.

An option to consider is whether you can keep your current home and rent it out. Even if you've never pictured yourself as a landlord, it might be easier than you think -- and it lets you hold on to the benefit of that low-rate mortgage. With local demand for rental housing staying strong, your home could bring in steady income while also continuing to grow in value over time.

Of course, renting out a home isn't for everyone. But if you'd rather not say goodbye to your 2.75% mortgage -- it's an option worth considering.
