Great city for families and settling down roots, but not trendy like Austin. 

New fans, new duct work, new dryer vent, new flooring, some new cabinets, electrical work, mold damage, sheetrock and texturing, sewage pipe broke in front yard from tree root (replaced pipe), leaking faucets (replaced), etc...

Unrelated, they also used soap in our hot tub requiring extensive cleaning.

pumping a tank should always be on the shoulders of landlord / property management and priced in with the cost of rent also you should make a note that tenants are NOT to use bleach and or antibacterial soaps as these products will kill the bacteria in the tank and cause a lot of problems down the road also it is a good idea to add  a bacteria of some sort to keep it working properly you can buy the over the counter stuff or just add some yeast mixed with water once a year or so I use bakers yeast every three to four years  

Many come to a market first to rent and see then about putting down permanent roots. 

I have some rentals that still have 1970s wood paneling, and I love it because when someone moves out I can simply wipe it down with Murphy’s Oil soap and I’m done.

They cited ME for it even though it’s their sidewalk there tree and their fault .I had city code violations issued and threats of s lien and so I had to pay to have stump ground the sidewalk pads torn out the roots ground underneath and new concrete pads poured .

That means your targeting a very unique tenant, one who is affluent enough to afford the rent, but has such unique circumstances (job moves a lot, etc.) that they don't want to put down roots and buy.

Usually you'll want to have something in there that tenant will report maintenance issues within 24hrs as well.So then when the drain clogs full of grease, tenant pays,  tree roots landlord pays ...

Grab a pump up sprayer and a 50/50 solution of water and bleach , add some soap to make it stick .
