If you still want to rent out your other bedroom you can have a tenant in the opposite side AND a roommate which would give you two income streams.

If investing in real estate was easy, everyone would have passive income.

Any tips on increasing income and lowering expenses?

Additionally, Airbnb income during this period could generate steady cash flow, though market conditions and regulatory risks should be considered.

I'm looking at monthly cost to seller vs. anticipated rental income, purchase price relevant to the ARV of the area and interest rate, balloon, etc.

I'm currently in search of lender to fund my new build.

@Luis Cerwin as others have stated, Nov - Jan is the worst time of year to have a vacancy.Majority of tenants live paycheck-to-paycheck, so all their income goes to Holiday spending starting with Halloween, then Thanksgiving, then xmas, then NYE.January is also historically the worst month for rent payments due to Holiday Hangover Spending.

What is the current market valuation of the property based on comparable sales (defined as similar properties, within a 1-mile radius, within the last 30 to 180 days, that are within 10% of total square footage)?

The owner should look at it more like a DSCR, and should be pricing the property and offering terms such that the income from the property is adequate to pay back the loan.
