Has anyone had experience with this or a similar company?

Why does she not have a job.I would not accept her unless the ex husband was willing to be a guarantor since her income depends entirely on him paying.If it were me I would be continuing to look for a working applicant that qualified.

I would also recommend talking to property management companies of where you're considering buying.

Go with another insurance company? 

Please feel free to also send referrals for other property management companies in the area with a solid track record of filling these kind of units.

That used to be a big deal, now not so much.....There was a long period where that was not really a consideration yet people continued to prefer separated rooms.And to the extent that energy costs continue to rise it is likely to be relevant again (and actually already is for a lot of people). 

Call with the pitch that you're local, started this business due to your mom's health, and that you'll outperform and out-service a multinational company that is likely taking your calls/messages in a Vietnam call center. 

:-) Outside the US I use the Corelogic calculator because our local insurance companies provide a no-frill version for free. 

The best way is probably a quitclaim deed (it might be different in your state, it would be worth asking a lawyer or title company), although I'm not sure exactly what the point of this is.

You get to learn and sometimes make mistakes with limited exposure. there’s great companies out there who’ll have your back as an employee every step of the way through the tough situations.
