In 2019, I launched my own revenue management agency to help Airbnb owners boost their income and achieve greater returns on their short-term rental properties.

But neither do you, yet you started with:"Short answer is "yes"  - which I consider misleading.And you manipulated the OP's question to fit your agenda.

Currently, we manage approximately 40 short- and mid-term rentals, in addition to a few long-term properties.

They quoted me a great rate also said I could close in a short amount of time.

This could be an opportunity to add value by offering to help with clearing or relocating those items as part of any potential agreement.Why This Could Be a Good Move for YouYou see long-term potential in the property, especially with the large lot and development possibilities (even if those are years down the line).As the current tenants, you have the advantage of a direct relationship with the landlord and familiarity with the property, reducing competition and risk.This could be a chance to lock in a property that you might otherwise lose if it hit the open market, especially in today’s competitive environment.Challenges to ConsiderIf the landlord is emotionally tied to the property or reliant on rental income, they may be reluctant to sell.Financing could be tricky, especially with today’s interest rates and the gap between the current rent and what a conventional loan might cost.The development potential you’re interested in is likely a long-term play, which means the property could be financially tight in the short term, especially if you’re only breaking even or slightly negative on cash flow.Structuring a Potential DealTo make this feasible, you’ll likely need to explore creative financing options that align with both your financial capacity and the landlord’s goals.Seller Financing: Propose a deal where the landlord acts as the lender, allowing you to make monthly payments directly to them.

Quote from @Andrew Lawlor: I've been actively investing in short-term rental properties for the past three years, managing one live property and another that will go live in two months.

Assuming these are for short-term loans, such as for flips, @Keith Groshans, you could do what we do and let the borrower keep the money and pay everything when they sell the property.

Quote from @Spencer Elliott: Long story short, land is on loan and I’m purchasing a manufactured lot as a temporary home/future ADU to my final build.

For $10K and a lower rate I'd be willing to consider delaying...but only if I knew that lender two was solid on closing in a relatively short timeframe.

A HELOC is a short term debt instrument.
