Please help me analyze this package deal!

[Katrina P.]

BP Family:

Here's the particulars:

2 homes sold as package for $30k

1st home:
Duplex (4bd/1ba downstairs, 1bd/1ba downstairs)
-The 4 bedroom is rented til 06/2013 for $700 per month
- The 1 bedroom is month-to-month and has been rented since 2010 for $375,

2nd home (directly in back of the first on the same lot):
-1 bd/1ba
-Leased til 11/2013 for $400 per month.

Other things to consider:

The seller will consider a land contract with substantial down payment. Insurance is a blanket coverage with other properties and is $550 per year. Utilities are $450 per month and taxes are $1919 per year. Currently two years behind in taxes, totalling around $5k. The properties have been listed for around a year. I'm interested, but want to know the thoughts of those who are more experienced? What other information am I missing/should I be asking?

Thanks in advance!

Katrina
