By looking at the numbers you gave me above, you can cashflow and your rental income is 1.1% to 1.3% of the purchase price.

With every unit you add the next comes faster because of increased income and financing opportunities (equity). 

Can you afford to give up that income that you are netting from the STR?

Selling the property offers a significant cash sum, enabling you to potentially diversify your STR portfolio by purchasing multiple properties outright, fostering a more passive income stream.

I would be interested to see what your credit and income would be because we have heloc options and I may be able to help.

Are you looking for long-term wealth accumulation, passive income streams, or short-term profits?

I would the adjust my offer to account for the repair.

The owner doesn't need to show alot of additional income for tax purposes but wants to sell the house.  

I recomend doing a web search on them in terms of their company and work social accounts.
