5 Plex Advice

[Chad Workizer]

First off I need some help understanding financing on a 5 plex. I've read that I can't do a convention 30 year fixed on property with over 4 units? If I can't what options do I have and how much higher are the interest rates?

Here are the numbers

PP: 170,000
Taxes: 1100
Insurance: 700
Rent per unit: 400
Year build: 1994
In good repair.
4/5 units currently rented
Tenants pay everything except trash

I was running calculators based on being able to get a conventional loan and was coming up with 900 dollars with taxes and insurance. I figured 80 percent occupancy which would mean always a vacant unit. So monthly income at 1600. After expenses I was figuring it to cash flow 400+ dollars a month. I have zero experience with 5 something like this so any advice would be appreciated.

I plan on managing the property myself.

Thanks
Chad
