I am seeing a decrease in nightly price and demand for these units.

I understood that rent prices are decreasing.

Should we refinance now if rates decrease even just slightly so we pay a lower monthly while we see through these repairs, then once repairs are complete have home reappraised and take out this equity to buy next property where we would live while renting out our current home?

Good renovations done at purchase should decrease repair and vacancy cost. 

The result could be limited, no rent growth or even rent decreases.

The cost per sf skyrockets as house size decreases. 

YoY is up 3.5%.Rentals - Availability by MonthThe number of homes for rent decreased MoM, also bucking the seasonal trend.Rentals - Median Time to RentMedian time to rent increased in November to 30 days.

Increasing for times when there is more demand and decreasing when it is slow. 

The interest is so much in the beginning, because the balance is so high, the interest decreases because the balance decreases.

This is largely due to the fixed nature of ongoing maintenance costs, which become proportionally more impactful as the park size decreases, thereby inflating the expense ratio.
