If you are an investor in NF what are your thoughts around this premise?

I notified my landlord of my intent to vacate the premises and moved out.

CRIME-FREE/DRUG-FREEADDENDUM HOUSING AGREEMENT In consideration of the agreement for housing the Owner and Agent and Resident agree as follows;1.Resident, any members of the resident’s household or a guest or other person under the resident’s control shall not engage in illegal activity, including drug-related illegal activity, on or near the said premises.

I know I can initially:A) ask for a double-security deposit (however few applicants can afford this, typically 'A' class tenants).B) Let the tenant know if they decide to use their security deposit as a last months rent payment, that if anyone ever calls in reference on your rental history that you will advise they pay rent late.C) Let the tenant know, if they damage the premises you will sue for damages as you broke the lease agreement @Mark Vieira This is something that tenants ask to do a lot.

You'd be surprised how big a part of the game simply taking calls is and how many realtors fail at the basic premise of being timely with their responses.

Understood -- however in Asheville for example, STRs are prohibited in most commercial and mixed use zoning districts, including the CBD.

Sorry, i wasn't sure if he was subleasing his entire premises. 

A lessor of residential real property, containing 5 or more units, who has received a security deposit from a lessee to secure the payment of rent or to compensate for damage to the leased property may not withhold any part of that deposit as compensation for property damage unless he has, within 30 days of the date that the lessee vacated the premises, furnished to the lessee, delivered in person, by mail directed to his last known address, or by electronic mail to a verified electronic mail address provided by the lessee, an itemized statement of the damage allegedly caused to the premises and the estimated or actual cost for repairing or replacing each item on that statement, attaching the paid receipts, or copies thereof, for the repair or replacement.

Understood. 

Understood Doug...thanks for your comment
