Raising the rent to market rate is not discrimination.

My strategy in Arizona has been adding bedrooms and renting by the room - currently getting 850-950/room in nice neighborhoods.

Just like when evaluating a potential purchase you should be performing the same due diligence with rents.

Rent it for what it's worth.

Another you could have done was to call a few other PM's in the area and get their take on the rent range.

Should I charge her a prorated amount of the original rent or the increased month-to-month rent for January?

How you guys handle if a couple wants to rent a room?

I am looking at buying a townhouse in NYC that is currently designated as an SRO with two rent stabilised tenants living on one of the floors and the other floor unit is vacant.

•Are the tax benefits of renting worth it in a situation like mine?

@Bryon Andrews was spot on in his advice too - do some Zillow and FB Marketplace surfing every few weeks to see what rents in the blocks near your property have been renting for recently, and track how those fluctuate over time for a few months.
