At the end i will add a list of items why adding a single ADU in single family zoned areas may not be the best RE option.The most common value add is via a rehab.  

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.

As someone with a military background, I’ve always approached investing like a mission—know your strengths, assess the terrain, and execute strategically.For me, starting with SFHs felt like the “crawl” phase before running into multifamily.

Our area is booming with growth with being nestled amongst 3 major military bases. 

Also, what others have said, the personal touches on what is in your place (e.g. providing all the essentials instead of having people buy TP, coffee, shampoo, etc.) and the quality of those items (no tattered towels, stained sheets, etc.).  

A savings to put deposits and another account for everything elseyou don't need separate bank accounts as accounting software will classify all of those items.

What is the speed of the internet, is it hot water (international property holders), is it AC.These basic clear descriptive items are great because if the price is fair and it clearly states the benefits.

But, on the other hand, if your life is very busy with your w2 job or you have a family to take care of, then maybe having a property management company will do you well and just worrying about larger items.

I would try to buy properties starting at a specific date so not large ticket items come up.

In my area (near the beach) its mostly families and they want cabanas, baby items, chairs, coolers etc that we do not provide but I have a local vendor that delivers and picks up these items and charges a few dollars per day for each item, and give me a 20% referral.
