back then, it was not whether you would make a lot of money as mych as if there was a different purchase that would produce a better return.  

It will show the rent amounts, who pays utilities and expenses they know annually.

After all PITI, utility, and services (lawncare and cleaning) costs I have $7,225.I set aside 25% of this for my maintenance fund.The remainder funds my lifestyle, wife has a Tesla, and quarterly vacations as well as business growth.In 2023 I am tracking to build 4 duplex units designed as room rentals funded in part from a recent land sale.

Landlords can enter a tenant's property for a variety of reasons, including: Making repairs or replacements Responding to a tenant's request Removing unauthorized window coverings Preventing waste of utilities Changing filters, testing, or replacing smoke detector batteries Inspections Helping with an emergency inside the unit Posting a notice of eviction"Research your state laws because some of your comments indicate a lack of understanding of the landlord/tenant laws where you are operating (like threatening the tenants to keep the security deposit if they don't respond to you, I doubt that is actually a valid reason to keep their deposit, or evicting for late payments, or charging the tenants for your warranty repairs because you missed your 11 month inspection window which was your responsibility, and it looks like your lease says you can charge up to 18% interest for unpaid fees, is that actually legal?).

The mortgage company gets paid off first, then in a traditional sale, the rest minus agent fees and utilities and closing costs goes to the seller.

Neither outcome is good for you.I give some approximations of each expense category in The Hands-Off Investor, but the best way to nail down operating costs is to look at the property's historical performance.For example, Contract Services and Utilities. 

While I don’t suggest that the smaller type investor purchase and utilize “exotic” vehicles like foreign asset protection trusts, family limited partnerships with outside controls, or Byzantine or convoluted maze of ownership entities, the more simple strategies of using Series LLCs, self directed retirement plans, and paying off their home mortgage to the extent of the Federal BK homestead exemptions can insure that a plaintiff attorney never even considers going after them.  

Lots of investors utilize rentometer.com.

@Rick Albert   I may get a lot of push back from the team but I split my utilities on my ADU the conventional way....each dwelling has its own meter for water, electric and gas. 

So far, it's been an effective strategy, and I've gotten some really good returns utilizing it.I think more property managers should consider it.
