Considering Package of SFH Rentals w/ LT Tenants: What to know?

[Alex Huang]

I was approached with an opportunity to buy a group of about ten single-family homes. The homes have long-term tenants in them and are all occupied. The private investor is looking to exit the space, so I'm trying to assess the situation.

Numbers:

Cost: $250,000.00

Monthly Rents: $5,174.00

Monthly Tax & Insurance: $1,076.65

Property Management: $517.40

The obvious other things to consider and investigate further are the CapEx and vacancy, which I don't know much about. My hope would be to get the info on the age of the HVAC, etc per unit. What other things should I be looking into and what other due diligence is mandatory in this circumstance?

I ran a $250k loan through a mortgage calculator. At 3.92% interest over 15 years, it means monthly payments of $1,839. Is that a fair guesstimate? Or is it a different beast since these are individual housing units?
