My experience with the smaller multi-family units has been that more occupants = more wear and tear on your property so the turnover costs are often higher than SFH.

Additionally, while rates aren't historically bad right now, they are higher than 4-5 years ago, and they will be even higher for you as an investor than they were as an owner occupant, which is what you were when you bought originally.I get that you are anxious to add to your portfolio, but that could be achieved without touching your first golden goose.Sometimes on BP, the push is to leverage every last spare penny, but that can be a risky game as the markets shift. 

The most reliable way is look at other STR's in the area and see what their nightly rates look like over the year and look at their occupancy rates. 

Be mindful that the nicer areas in AA Co have particular neighbors so follow occupancy rules. 

The key is to analyze occupancy rates, seasonal fluctuations, and what type of properties perform best.

Occupancy permit.

Some of the best performing properties can have an occupancy around 60% for the year and sometimes lower.

After two years of occupancy, qualifying for the tax exemption, and benefiting from appreciation, we chose to sell and reinvest the funds.

Quote from @Lucy Ahl: This deal was not for owner occupant but for a flip.

As a savings of a few thousand dollars on furniture, could determine if your occupancy rate is 65% versus 70%...If the revenue is $50,000/yr that's $2,500 in one year (which could be the breakeven for that specific line-item expense).To determine you total breakeven point occupancy rate, and not just related to the furniture, take your operating expenses plus your debt service and divide it by your effective gross income.
