The absolute best place to stay is with your dominican suegra, and don't kick in a peso while staying. Eventually, you'll find a place, and she will either be happy for you (if she doesn't need any money), or so sick of you being taca?o (if they don't have the money) that she will know that you aren't the family lottery.
In case ?1, you can throw a big house-warming shindig once you.re settled as a thank you, and in case #2, don't breathe a word about your new place.
Either way, you win.
