I am wondering if this can actually be classified as the first floor unit. 

Just floors and paint will eat up 2/3 of that, you will still want to put in new trim, new vents maybe, and a few other minor items. 

The house is two story home with laminate flooring all through the house except the bathrooms and kitchens, I have been taking a very good care of it without any scratches so my concern about renting it is if the floor gets damaged and I have to redo it all over before putting it back on the market along with do HVAC repairs (It is 12 years old system and running great but I am sure in the next few years will need some care in Texas heat).Currently, I live like 12 miles away from this house, Any thoughts would be appreciate it.

As per pictures, new kitchen, new baths, refinished floors, converted family room into master bed and bath.Top quality materials at designers costs thanks to my partner.

We did all new electrical, HVAC, plumbing, roof, foundation repairs, drywall, paint, flooring, three new bathrooms, etc.

If you can do this by having a renter pay most or all of your living expenses while you live for free or close to it on a different floor you are setting yourself a solid foundation.

Example: if you need to add a fresh coat of paint and install new LVP flooring in a room, it would be wise to paint first and then do the flooring last, so you don’t get all that paint all over your new floors.

Also make sure to tell your insurance provider about any other damage that was caused as a result of the leak (flooring, baseboard, drywall, paint, etc).I've only filed 1 claim and it was on a roof, the cost to replace was around $10k.

I'll help fix cabinets, mop floors, heck I'll walk your dogs if I need to.

It's like a bunch of boxes with no real flow, with multiple floor levels, and is awkward at best.
