For example, for commercial MFH I typically implement the following from his analyzer:Conservatively estimate expenses as 50%2% annual rent growth (again, being conservative)--I know this depends on the marketVacancy % = 1/[number of units in property]--ex. 1/6 unit, 1/8unit, etc.Ernest Money Deposit = ~1% of Purchase PriceCharge an acquisition fee since I'm procuring the deal = ~1%Charge capital transaction fee = ~1%Charge Asset Management fee = 1%Refinance after X years and sell after Y yearsGauge whether a deal is "good" if: Average Annual Return = 15%, IRR = 15%, Average CoC Return = 9%Can these measures be taken for 4plexes as well?

You pay all that with real money out of your pocket if you can't procure tenant ASAP Even after it rented, there is no guarantee that tenant won't move out quickly because he doesn't like something - that's why banks consider that stabilization of a property takes two years.From my experience, there is always something wrong going in the first 5-6 months even with perfectly move-in ready properties.After all, if your Rent is projected at $1250/mo the price should be not higher than $125K.

I’m hoping this is avoidable because my broker did not provide me any resources that helped procure any of my deals

-Should I tenant screen for all adults in the house or only those responsible for paying the lease as agreed?

It seems procuring financing to purchase notes is difficult if not impossible. 

The initial model we have in place at the moment is all procurement, construction, and property management fall under my responsibilities while the investor strictly provides capital and waits for a check in the mail.

I tenant did not pay rent and left the property in bad shape, I got a judgment against the tenant, how do I file for garnishment?

Whoever shows them the property is the procuring cause of the sale, and they are due the commission.

Personally, on small MF investments of 5 units and up, a debt play may be the wise route where you simply borrow the capital to procure/rehab the units and then pay a reasonable interest rate to the lender.
