It turns out the boyfriend has been charge with abusive behavior and has been issued a restraining order by the courts that essentially evicted from the home.Due to the fact they both did not strong credit, I had initially taken 2 months rent from them as security deposit, with the understanding that 1 month would be returned at end of 1st year lease if they decided to renew. 

Also, if I am self managing, can I log 16-24 hours per day if I am doing things like monitoring security cameras throughout the day, receiving and delivering renter's mail, responding to whatever needs/concerns renters may have, etc., and if I am available to my renters after hours / through the night?

I actually ended up securing a lease on the third, but took a 2.5 month so I'm already concerned for next time ha.

Will there be a security system or security cameras on the property?

They went to go stay with their nearby relatives but I do see them coming in/out of the house through the security camera.   

It’s also prudent to review and update your properties' safety measures, such as installing fire alarms and security systems, as these can sometimes help reduce insurance costs.

In California, the law limiting landlords to a maximum security deposit of one month's rent for unfurnished properties and two months' rent for furnished properties went into effect on July 1, 2024.

How many times can I have repairs done in their unit and they cry afterwards that they didn't know they needed to properly secure personal items?

Reading through some other forum posts, it looks like there are much simpler partnerships, entities, or offerings that would meet what I am trying to do:My Role:-Decide on properties to purchase, mostly SFHs-Establish LLCs or other business structures to hold the real estate and distribute returns-Purchase properties, using loans as needed depending on the ROI/cash flow desired from investors-Act as property manager for the properties-Depreciate properties held in business entities to minimize taxable income to investors-Distribute returns to investors-Create investments that have high cash flow (CF) and low appreciation (App) , moderate CF and App, low CF and high App-Find investors from connections, friends, and family with no public advertising-Advise in a minimal capacity on tax and real estate strategies-Send investment reports to investors-Be fiduciary to all investors-Receive compensation from PM and other management work I do related to the investmentsInvestors:-Can be non-accredited -Invest as little as $1000-Can use retirement accountsWhat references can people recommend for me to learn about business structures, partnerships, securities, taxes, or other topics to get me started on learning what will work for my goals?

Putting holes in wall for any reason is not normal wear and tear and will be pulled out of their security deposit.
