Nevada is less strict in general, and a great place to start, but they also have less inventory and higher prices.

I want to cash flow $5,000 / month by the time I turn 30 years old and, from what I've researched and read, small multi-family properties provide the greatest opportunity to do so as they don't strictly rely on one tenant for the property to be profitable.

Every place is different - go strictly by the book or it'll come back & bite you.I add $10 per day as soon as allowed, BTW.

While setup can be a little tricky if you don’t follow instructions to a tee, once configured it’s literally set it and forget it. https://www.amazon.com/BRAEBUR...In addition, there are smart oil tank tools as well, but that puts you right back in the business of having to install and support “smart” devices, own the network, or get your tenants to agree to put your devices on their network and not decide to change the network name/password at the point they realize you’re using their network to regulate their heating. 

This means it can hypothetically carry a 4 unit multi family max at the regulated density but with FAR restrictions of  0.30 meaning the total living sq ft will be limited to about 4200.

Also, are you loosing money due to repairs/re-leasing, or is it strictly break even? 

Her original lease which I inherited clearly states no smoking was permitted and when I took on the property in May I issued her my rules and regulations, which she signed, that also stated no smoking.

You can hire and fire an employee if the employee/property manager isn't doing a good job.I also know how PM companies who do NOT own any properties and just strictly manages properties/income/expenses do for their clients.

As a result, towns have denied permits in some places and have promulgated zoning regulations to prohibit them in others.The other thing to be aware of is that at least in some installations, they'll be similar to mobile homes in that the land is leased, not owned.
