2 Homes rented in Hammond, IN... good deal?

[Chavis Atkins]

Alright, well I have 2 homes that I want to put under contract as the owner has given me the terms he want and I want to shoot this out to buyers but I'm not quite sure if I have it structured right.

CURRENT OWNER PROPERTY CASHFLOW (MONTHLY)

$1,600 Gross

$400 Taxes

$120 Insurance

$200 Maintenance/Vacancy Expense Budget

$880 Net per month (While keeping back unit renter as a universal handyman for free labor while he gets free rent)

POTENTIAL CASHFLOW [(MONTHLY) INCLUDING RENTING BACK UNIT]

$2,000 Gross

$400 Taxes (2,400 a year per home divided by 12 months)

$120 Insurance

$200 Maintenance/Vacancy Expense Budget

$1,280 Net per month

PROPERTY SALE

$72,000 Sale Price

$30,000 Total Down Payment

$5,000 Assignment Fee to Calai Investments

$42,000 Mortgage on both properties

Ultimately the owner wants to sell both homes all cash for 66k. But I gave him the idea of doing a seller finance and he wanted at least half down of the purchase price. I think I could get him to go 5k less than what he wants down but I never sent out a seller finance deal before so I'm not sure if how I got it setup is right for the buyer. 

1 property is a 3 bed 1 bath with basement... no garage but does have AC and the other property has 2 units: 3 bed 1 bath in front with basement and 1 bed 1 bath in the back. Owner willing to do 4% on the mortgage amount. Thing is too the owner wants like 900 a month as well and with the expenses that leaves the buyer with little unless he rents out the back unit. All the units are occupied currently but the back unit of one has a deal with the current landlord. Any more information on these homes needed to help me structure this right just ask.
