They develop, they build, they finance, they property manage, they will have HAO, cleaning crew etc. etc. etc. so the subsidiary companies make money every step of the way.From investor perspective: The investor pay $15 K to reserve the right to purchase 25 multiplex over the year of next 5 years. 5 each year.

Once the work was complete, I refinanced to pay off the hard money loan and held the property as a long-term asset.This duplex also marked the start of my short-term rental journey—we ran our first Airbnb from one of the apartments before scaling to bigger projects.

The only purpose of the account would be to collect payments and pay bills like taxes and insurance on assets held by the LLC.

That means paying all cash isn’t an option unless you plan to bring another $600k to the table. . 

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

Quote from @Jeffrey Duck: I see no reason to pay an attorney for this, but it's your dime.The current lease was between you and Person B.

Pay your attorney and your CPA for a customized advice. 

I kept throwing all my RE profits back into the next deal or paying off a short term loan.

If it is not adding up, and you can find an attorney specializing in that type of thing, it may be worth paying for a little of their time.

So that with paying my investor 6.3%, they will get a passive income of $2,532 every month ($30,384 every year).
