If the unit has good air flow, such as you would find with a forced air HVAC system, it will lessen the chance of moisture build up.If the tenant had blocked the sliding glass door and surrounding area with excessive furniture, boxes, or clutter, then that could lead to moisture getting trapped.

Finally, get the big box stores like Lowes, The Home Depot apps,  whatever is in your area and look up costs of supplies.  

As a Seller that's what I had to supply my Buyer each time I sold,,, sold 3 properties in the last 3 years.. 

The supply of sub $200k SF properties is limited to existing inventory, as new construction starts at about $300k, with the majority in the $300-$500k range.

It is difficult to add new supply to the market in many coastal areas.  

So there are two things have driven me to consider the build-to-rent approach: what I just mentioned about supply, and the portfolios for sale that I began this thread with.

Golden West is just a brand name for Clayton Homes, who supplies modular homes to Cutting Edge for our clients who have more limited budgets.

I used bleach, ( bleach and urine make a lot of ammonia) , I rinsed it off and then put down huge boxes of baking soda spread on the floor and let it dry and them broomed off.I used gallons of peroxide I bought from a beauty supply place and poured that peroxide full strength on the floor and let it sizzle.. it helped open up the pours in the concrete so the ammonia from the urine would neutralize. 

First, I'll be furnishing the place to the tune of, say, at least $20k in furniture.

Lowe's quoted us $13-15k for the same layout we ended up purchasing through Wholesale Cabinet Supply for $6k.
