Well his boss was impressed with my real estate and finance skills so I ended up working for their company well it turned out their company was wholesaling houses they didn’t really flip many homes.

How did you finance this deal?

Seller financing?

It is purchased with 20-30% DP and financed by local banks.

Maybe pay for an appraisal up front or if you are financing, the lender will do one and if it doesn't appraise, you can walk away with no consequences other than your time.

You can use the cash value in the policy as a source of funds for financing, and it is an asset and liquid through withdrawals or loan by borrowing against the cash value. 

Her idea at present is going to be to purchase the house herself (using traditional financing - high interest rate) and make the payment affordable for the family's rent to cover by arranging the sale well below market value and putting up a down payment of 30+ % of her own money, resulting in a PITI of ~1500.

With house hacking you'll be able to close with less cash out of pocket and you'll have favorable owner occupant financing (lower interest rates). 

And was this for a conventional financing?

What type of financing are you looking for/what does the deal look like?
