For our basement unit we only have two but that is because we do the laundry right away as we live above so there is always a spare in case of an emergency.

If you want to house hack make sure it cash flows when you move out, you can afford your portion of the payment after rental income, that it's in a good area, and you have an emergency fund ready and you'll do fine!

Texas was one of the first states to emerge from the "Lock down" due to COVID.

I like the PWC Emerging Markets analysis for this. 

Looks like you were on the initial phase of an emerging market/section of the city. 

That being said, there are many neighborhoods just outside the city that could have a nice return for you - just depends on your strategy.Also, being out of town, I would try to assemble a team before buying (plumber, electrician, etc.) because you are going to need people that you trust in case of an emergency.

, long term relationships with proven Contractors (licensed, insured; also unlicensed for specific, locally allowed tasks), and has been very hands on with inspections, small and large repair projects, and a wide assortment of Emergencies.

The market doesn’t matter I’d say the strategy you implement on the property matters , doing the proper due diligence before purchasing and also having cash reserves for emergencies.

Have you reached out to her emergency contact to many sure she’s alright?
