Help. Seller owes what the house is worth. What do I do?

[Geoffrey F.]

Hey BP fam,

Excuse my noviceness but I would love some  of you folks that have more legwork to help me decide if this is a deal or a waste of time.

Call from a direct mail

1800 sq 4/2.5 bd/bth - $120k - $130k - Sold comps and Seller says he owes about $120k with a mortgage of $1250/Mo. Its in good condition well kept 10-15k repairs.

Any advice or help would be so appreciative.

If I don't have anything here I understand. 

Seller is very motivated and I would like to help and give him great service. 

Thanks in advance!

Geoff,
