Unfortunately, there are often cases of a landlords treating their tenants poorly or not maintaining their properties.

Once you know you have a problem with bed bugs, you can treat with the silica dust in all the wall voids and cavities.

I assume that when bank does the appraisal, it will still treat it as a single family house and uses the comps to appraise.

Treat this as a business. 

I'm not an expert with Airbnb, but I wouldn't treat it much different than my LTR. 

They can easily spread to other rooms or in multi-unit buildings, into other apartments.My thoughts:  have the entire house treated, and keep the old tenant's security deposit. 

You went over the lease, treated her with dignity and stated your rules on whats important to you.

@Gevin GlinesThere was a recent post you created about house-hacking.House hacking makes your tax situation more complex.You purchased a property that is treated as both an investment property and a personal residence.

I seriously look forward to hearing how that tenant treats you and if your succesful in that plan.

Most individuals are looking for cash flow investment properties I recommend that they treat their purchases like you would a flip.
