any Advise help!! we found bed bug and we must mover!

[Ornuma Panmunee]

Advise needed. I own a 2 bedrooms condo. Our downstair neighbor had bed bugs. they are still in the treatment. the condo management sent Orkin guys to come check at ours, they found nothing. 2 months from there, we now found bites on our 18 months old son. And yes, there are bed bugs. we had the 1st treatment on Friday 23rd. my son still has new bites every now and then. tomorrow we will have the 2nd visit. here where the problem begin. my husband is already freak out (mostly because of our son is too young) amd he want to move out. he want to sell this condo or put it for rent. I DON'T WANT TO SELL THIS HOUSE. I'm now a stay home mom, and this house is only thing I own. we brought it 2 yrs ago under my name only. we were both working and made about the same money but he has huge student loan debt and he never pay, only has IRS take his tax returns. I was planning to start a new load for the 2nd house but both working parent with a newborn baby was a struggle. so I decided to left my job. which I think was the bad decision because now I know that I can't get the 2nd house to invest as I wish. sum this up, me and my husband, we both can't get a new home loan. But I want to keep this house and dont want to move to the rental house. we only have $10,000 in saving. and $5xxx something in my husband IRA. I been searching on Auction.com hopefully one day I can start my investment. ok here the questions. do you think what's the best move for me right now in this situation? should I look for a house we can rent for the price that cheaper than we are paying our mortgage right now? (but the cheap rental house come with not so great area. I had seen some rent to own options, is that legit? and how it's work? and other options help!! best orn
