If most VRBO's do have a pool then make sure you have the proper insurance follow regulations (fence around pool etc) maybe even have an alarm on the pool that would buzz in the house if surface water disturbed like if someone fell in.Then have a professional pool company maintain it.

Investing in student houses looks great on the surface.

Most of the books barely scratch the surface and are little more than an intro, not enough to actually invest in them. 

@Hector Rosero I need a bit more info to really assist here, but on the surface, it look like you should be able to move out of the home you live in now and into another property since you've lived in the property for 2 years.

There’s a lot more beneath the surface.

I would love to start here in Las Vegas as opposed to out of state however on the surface it didn't look possible. 

I would paint it and replace any carpet, I have tried a few other ways, but none have been 100% fixes, but paint & Carpet and wash hard surfaces.  

Any soft surface like carpets or drapery is gonna need replaced.

Our experience has been that in cases where there has been prolonged smoking by the prior occupants, the only way to rid the most affected areas of the odour and harmful residues accumulated on exposed surfaces is to gut these parts of the property back to the studs.

You are responsible to keep all walking surfaces in good repair and free of hazards.
