The "conventional" un-conventional method is to buy "subject to" the existing mortgage, flip, then satisfy the existing lien on your sale...

@Justin Lee I got a home equity line and used it for multiple small conventional FHA loans.  

We have been through underwriting and are approved for a conventional loan. 

Input greatly appreciated.....I have cash to fund the rehab portion of a flip..my partner now wants to buy the property with a conventional second mortgage that she has already prequalified for.  

If you have an amazing deal, you could maybe fix up the house and refinance to a conventional loan. 

I have laid out a rough draft plan that should allow me to acquire 35 rentals ranging from purchase prices between 65k-100k by the time I turn 31 years old with rental rates ranging from $850 up to $1300 a month (putting at least 20% down on each home with a conventional loan, depending on the condition trying to get a conventional rehab, and using the positive cash flow to pay down mortgages/use towards down payments on more rentals) I have read multiple books from millionaire investors such as Manny Khoshbin, Donald Trump, and the like.

If you are living in the city and are only planning on investing (and not owner-occupying), with conventional financing, you will most likely be required to put down 20 to 25%.

Conventional loans2.

If you couldn't refinance out of it then I would maybe look at conventional.  

Weve been approved for a conventional loan but we are not able to get funding due to the deed restriction.
