That's a very small amount to finance. Most lenders won't be interested, though certainly give Carrie's recommendation a try.
There are a couple of other alternatives. You could always offer owner financing. If you don't need all the cash right away, you'd just create a note, same as a mortgage. It can be for whatever length you want, and at whatever interest rate you want. (Just watch out if Massachusetts has usury laws.) But, for instance, $25,000 at 6.5% for 7 years would equal monthly payments of $371. Or 6% at 30 years would come to monthly payments of $186 a month.
Another possibility is creating a note with the intention of selling it for cash. You'll still have to wait a bit to "age" the note--to prove to whoever you're selling it to that the buyers are dependable. And you'll have to sell the note at a discount. But that's a way to get all your equity out in perhaps a year.
Another possibility is for the buyers to take out a personal loan, rather than a mortgage.
Or some combination of the above--such as the buyers taking out a personal loan for $10,000 and you creating a note for $15,000. So you'd get $10,000 up front and $15,000 over time.
Or the buyers might find some private financing. Someone willing to lend them the $25,000 at a reasonable rate of interest. An investor might even do it out of a self-directed IRA. The buyers themselves wouldn't be able to use a self-directed IRA (unless they're buying as an investment), but someone else could buy it from you, then resell on terms to the ultimate buyers.
And there are plenty of other ways to finance it, as well. The ideas above just barely scratch the surface.
Hope that helps.
