If it matters to them, try a Deed without Warranty (google).I have a fair number of cases in tax court at different levels. 

I did do a fair bit of remodeling myself while I lived there.Best purchase we will probably ever make since it was 5k down for 160k duplex (worth 230k now after 10k or so in remodeling and increased rents) and cash flow of $800-900/month now!

I think a common thread here is good communication and boundaries: I'll work with her to find a solution, and if we cannot make it work financially, we will have to find different accommodations for her.

Had to communicate with the local division, but ultimately, it was wiped away and I was able to sell the property within a month.  

In our specific funnel, once a prospect shows interest in our services, and ultimately matches our criteria, let's just say we don't let them slip through the cracks...Once in the funnel, we automate our communications with them until they become a customer... this includes direct mail (yes, you can automate usps direct mail), Ringless voicemails, texts and emails.

Should I call the company to find out more information about this or communicate with the seller to see if they know?

To be fair, I've never had a home warranty for either my personal home or any rental properties.But I've know a few people who have had them for their personal homes and they sounded like nightmares.These are the complaints I've heard:I'm sure this can vary by company, but it's typically a $75 service charge every time a repair person comes out. 

Do you know the fair housing and tenant laws?

I always encourge folks to just pop on Lendinghomes website they have a great pricing matrix you can check and those are about as good of HML rates as you can get.now to be fair HML rates have been hammered down.. with all the free flowing money.. but those great rates as you will see in the matrix are not fico driven they are experince driven or cash into the deal driven..

I don't know the area but $1,700 a month for a $125k house seems off, and if you are in PA I believe that your property taxes are fairly high 2%+Also expect to pay points either way with a HML or conventional lender, the interest rate for conventional will be significantly lower.
