Depending on other circumstances I would not include a free clean with a week long extension. 

I really think that the biggest pros and cons depends on YOUR goalsI self manage my properties with the help of a VA and I like that I can be hands off now that my VA is trained.

Investing in residential rentals can offer dependable cash flow and gradual appreciation, which could help fuel your interest in bigger projects down the line.

Does it vary depending on property type and unit count (SFR vs Multifamily, vacation rentals vs. long-term rentals)?

It really depends on experience level.

I love being able to turn personal properties into rentals as they required a small amount of cash for a large asset to have someone else paying off.It really depends on your long term goal, but ours is to use these "retirements baskets" into reasons that early retirement at 44 is successful! 

Recommend cash for keys here (like you already tried) and getting them to sign a termination of lease.If the lease period ended and they are on month-to-month typically you have leverage (depending on what your lease says, or local laws) to end the lease at the end of the month given prior notification.

They would bring the downpayment and equity division depends on the deal but being new I would give about 60% away just to get in and out of a deal

Thank you in advanceDepending on tree type might be able to trade or sell for the workCost for all utilities and street will vary depending on the type of road you will have inverted or crowned. - how many catch basins you will need, hydrants   - etc.Very important you must utilize both sides of the road to maximize your effective cost for the road and utilities when building.

But will just depend on what you are trying to establish.
