Peak months (winter/snowbird season) see higher rates, while summer and hurricane season may dip.

Routine maintenance and unforseen maintenance costs; insurance rates (they are increasing all over), property taxes and vacancy rate.

Quote from @Fernando Martin-Gullans: Hey y’all, I’m a retail investor with 2 SFH rentals worth a combined ~$650k looking to utilize some of my stored equity to buy more out-of-state properties, but I’m not quite sure how best to proceed given that my interest rates are incredibly low (leaning me away from refinancing) and neither property is owner-occupied (which I believe prevents me from using a HELOC).

This creates two loan payments ($100,000 of equity and $300,000 on the new mortgage).Key NumbersHome Equity Loan Interest Rate: 6%Mortgage Interest Rate: 7%Rental Income: $3,000 per monthExpenses (management, taxes, insurance, maintenance): $800 per monthIncome and ExpensesMonthly Rental Income: $3,000Monthly Expenses: $800Monthly Mortgage Payment: $2,000ExplanationThe investor earns $3,000 in rent each month.They pay $2,000 on the investment property mortgage and $800 on other expenses.This leaves $200 profit each month or $2,400 per year.However, you have to pay $6,000 interest on the equity borrowed.This leaves you with an annual loss of $3,600.While the rental property generates positive monthly income, the interest cost of borrowing the initial $100,000 results in an overall loss.

Only difference is the $10K is in your bank and the interest starts so you are paying on the full $10K over how ever many years they offer.Lastly, depending on your first mortgage rate it may be best to just do a "Cash out refinance" becuase its over a 30 year mortgage and the rates are lower then both Heloc or Heloans. 

Nightly rates, occupancy and amenities.

Georgia Amendment 1, which authorizes the General Assembly to implement a statewide homestead property tax exemption, has far-reaching implications for both current homeowners and the broader real estate market.Short-Term Positive Impacts for HomeownersThe primary benefit of Amendment 1 is the cap it places on the annual increase in a home’s assessed value, limiting it to the statewide inflation rate.

Your primary's rate is low and instead of plowing down $88k on the rental, look for another property for your portfolio.

(To clarify, the metric I'm talking about isn't true cash-on-cash or cap rate, under strict definitions.

(I also don't understand how you have a hard money loan with a rate of 7.25%...)offering an equity position that you then buy out in just a few years seems like way too much complexity and risk when you say you just need 30K.
