Last tenant cooked some amazing Indian food but with the spices etc the new tenant is concerned the odor may still be prevalent when they move in. 

My third rental was also running tight on budget and I ended up replacing the oven and water heater AFTER the tenants moved in and heard a loud pop and smelled a foul odor, respectively.

It is easy to run foul of discrimination laws and the fair housing act.

They also state that ANY pet odor or damage will come out of the security deposit.For the LOW, LOW price of $199, I, AARON MONTAGUE, who once owned a dog as a child, will certify YOUR BELOVED PET as a service animal to get that nasty landlord off your back.  

If mold can be seen, if a musty odor is present, or if there is good reason to believe health problems are being caused by mold, a careful inspection of the home should be conducted.

It helps neutralize odors and can kill some mold spores.

You can discriminate for body odor, facial tattoos, and even hair color if you choose.

Unless you are waiving any contingencies you or someone you trust will be seeing it at some point so really no harm, no foul.

You are not required to have Tenant permission.I recommend an inspection after 3-4 months and again a couple months before offering them renewal.I do not recommend trusting the Tenant because it's too easy to hide something under a piece of furniture, not take a picture of the broken window or missing screen, and you can't see odors or extra tenants or unauthorized animals.If a Tenant refuses to allow entry, that's a lease/law violation and should be grounds for termination of the lease and removal of the tenant.

So there are no other complications like odor etc..
