But you could maybe assume the loan and get a secondary loan for the rest.

Quote from @Hector Espinosa: Hi,I'm negotiating a seller financing deal which may be my first one and would like to ask for some advise about and what are advantages and disadvantages about seller financing deals.These are the seller financing terms:House Price: $330,000.00 USD​ (Sellers still owe ~$301,000 USD)Down Payment: 5% = $16,500 USD​Loan Amount: $313, 500​ (Monthly payments will be amortized as a 30 years loan​)Interest Rate: 4.531%Balloon Loan Term: 5 YearsMonthly Payment (P&I): $1,594.24​Closing Costs:  ~$3300 ​Zip Code: 74105Observations:       * HVAC requires an update but pending to inspection (replacing with a new one will cost ~$10,000 - $15,000 USD )     * Expected Rent Income: $2,000- $2,300 but this is has been really complicated to get a good estimate because is all over the place in the different sites I have checked

If your DTI is already high, taking on a higher loan amount might not work.

unless its a VA loan, you cannot.

You could build that in phases and finish the first 4 and then get your lender to do a construction loan on phase 2. 

Lease options are the vehicle of choice here, until I sort out how to get to the other side of the ceiling imposed by debt to income ratio.

The ideal home price for you will depend on: 1) downpayment size 2) risk appetite, 3) preference for more cash flow or appreciation.Given our price points, our investors need to have 35-45K to start, on average.The typical cash-on-cash return on our properties net of loan payments, insurance, taxes, and property management fees is 6-8%.Ultimately, you can obtain financing from any lender, although we have partner lenders that can provide very competitive rates.

Do you ave 2-4 lenders that you've built relationships with and do you understand their terms for purchasing the land and the construction loan and the exit strategies if you need to hold the home a while before you sell to a buyer? 

Jackson is very active for investor loans.
