Yeah this seems reasonable, I would always check with local regulations, but can always add into new lease, prorating the gas bill based on square footage or number of occupants in each unit and passing that cost on to the tenants.

Not to say you are implementing these things to share with LPs to help build trust, but if you had me interested in investing, then went down a rabbit hole of all the ways you are protecting the investment, I would actually start to second guess my investment.But more to your practical question: the best way I have seen this done typically requires a fairly large scale. 

I am a non-practicing architect, so the challenges might be what makes it interesting.

1 day: $252 days: $503 days: $7510 days: $25020 days: $500I can assure you, no court will award you $500 in late fees.Best practice is to create a single charge.

At times, the seller may back out, you may not get financing to go through due to changes of lending practices due to (Covid19).

I got so excited when I heard about cost segregation analysis as a way to get the maximum depreciation paper loss during the first 5 years in conjunction with having a spouse who is a "real estate professional" status for tax purposes.The way I found out about cost segregation analysis is listening to podcasts (as my usual practice during my marathon 2 hour commutes).  

As with many things in my experience CLTs are better in theory than practice.

However, there is a strong correlation between tenant-friendly and more red tape and regulations on short-term rentals.
