I’ve spoken with a few agents who estimate it could generate anywhere from $150,000 to $300,000 in revenue, which is a big range.

After 45 + years as a real estate investor, broker, lender, fund manager and syndicator, I’ve become aware that the “dream” of many investors and investor “hopefuls” is to be able to generate enough cash flow to live off their real estate holdings and accumulate enough wealth to make “work” optional.

A real estate business can also potentially generate a SOLO IRA or something like that. 

. - if I use my cash, the investment needs to generate > 5%.

It gives you access to funds at a relatively low interest rate, and you can repay it as the rental generates income.

If you are using STR, REPS, or self rental with material participation to convert to active or nonpassive income, you do not have to do this if you have passive business invesment that produce passive income that will exceed the loss generated by depreciation.

However, there are still plenty of tax benefits when it comes the income you generate from your multi-family property that you can deduct from. 

In New Hampshire, title laws are strict, so we couldn’t move forward without obtaining a signature from a living heir.The title company dug deep and eventually located a distant relative—a niece of the deceased owner, two generations removed.

I am sure there aren't many comps that this would generate.

They just generate chlorine at a constant rate depending on the system setting.
