Someone else is paying all the interest compared to you paying it now.

Average is between $700-$900.We base all our income comparisons at $750 a unit and you should be caahflowing at least 50% of your gross rental income compared to the purchase price.

Go to unit with new tenants, give them "tenant training" on water shut-off, fireplace, fusebox, etc., and wish them well!

One of the strategies mentioned is to offer 2-3 choices to tenants so they compare the choices rather than comparing your rental to others in the area.

Residential lenders won't touch it, and commercial lenders tend to value it with comparables (like a residential) instead of the income approach because it's more similar to a 4-unit than a 20-unit apartment. 

I have two refrigerators that make ice but do not dispense water.

Raising your limits and getting an Umbrella would be relatively cheap compared to the overall cost. 

Call the city ask about the taxes, current and after the sale, ask about water and sewer, ask about the utility bill-verify everything.
