There are down payment programs for duplexes, i have not searched or tried to do a 3-4 unit property. 

Down Payment: 20% of the purchase price, equal to $43,0003.

I decided to buy the property from my grandfather using a gift of equity, which allowed me to take over ownership without having to come up with the full down payment and pay for the tax lien and his closing costs.

Medical Payments: Provides coverage for an injury suffered on the premises.

Which means that they pay you a down payment and you finance the properties to them.

We've enjoyed digitizing all payments, streamlining service, as well as infilling new homes.

You only need a place to track tenant information, payment history, maintenance, etc.

Current value of paid off property is roughly 350k , looking to borrow 75k-100k down payment to  purchase a 275k commercial property.

I had specifically asked for numbers including mortgage payments and they emailed to me.

You likely only made a down payment of 3-20% ....but you still get to write it off on the full value across 27.5 years.So 400k/27.5 = 14,000 ish a year of a write off where during the year you didn't need to incur an actual expense, no cash outflow.
