Texas accessibility standards ADA For us) don't require a tub in a residence.

They also ran some plumbing out from the corners of the home to run all the gutter water out and away from the foundation.

Do all tenants going on the lease need apply and meet qualification standards?

The only other idea if the ozone machine doesn't work that I can think of is calling a water damage / smoke damage restoration type company. 

My partner and I are in negotiation for a 6-unit property in NE Ohio, below are details: 4 rented, 2 vacant / average rent $735 (4 rented units $720, 2 vacant $775)Owner pays water, sewer, trash2 br, 1.5 bath, roughly 900 sfGarage with door + extra parking areaRoof in good shape, air and furnace in good shapeRealistic gross all units filled: monthly $4,400 / yearly $53,000We walked through both vacant units, very clean and basic.

Definitely check all windows, ceiling, roof for water damage.

Here are the numbers:3bed 2bath - split level single family home sitting on 2 acres of land, 0.5 miles from the water.

They say this is standard but I find this hard to believe.
