They look wonderful and would really push my rent up another 100 bucks along with some minor updates to the kitchen and bathroom (faucet, fixtures, vanity, toilet, paint cabinets, etc..)  

Cabinets and bathrooms are from the 60/70s.  

At lease put a a hard box, well anchored into a locked cabinet to protect the keys.

Can a concrete floor, painted drywall, or kitchen cabinets hold in odors??  

I should have added I guess that the rehab costs (roof, deck, floors (refinishing), kitchen (cabinets/counter/floor), bathroom (tile), deck, AC unit, water heater, some minor modifications to the interior space, complete painting on interior and exterior, new front and back doors, some landscaping) would cost about $40,000, which would put me all in around $90,000.  

I wanted to purchase the kitchen cabinets, countertops and appliances myself seeing as I will hunt a little harder than a GC on a good deal.

I really haven't done much but the time it takes to simply paint cabinets alone is forever.  

I can understand many reasons why people may want to limit or eliminate pets - smells, afraid of dogs, reptiles, whatever - but I have bought plenty of rentals and the majority of damage in these properties are done by wayward people - holes in drywall/doors, broken kitchen cabinet doors, filthy appliances, etc. 

You might find kitchen cabinets and other big ticket items that keep your budget down vs. buying retail.

I currently do not own any real estate, and am working on building a custom cabinet business.
