The problem with a temporary work around, they tend to become permanent. 

However this credit union is not willing to cash out any equity only offer me an equity line that can be converted to permanent financing.

I have had other investors recommend a line of credit but I seem to be finding that it would still operate the same when I try to roll over that credit into permanent financing in regards to LTV and the seasoning period..

I am finding it difficult to get a Construction to Permanent Loan from a conventional lender. 

If it is, you could build it first and then she can move permanently into that at a lower rent.

I am just fearful of the permanent W2 jump I think.

I've got a recently renovated paid off 1994 doublewide manufactured home on a permanent block foundation just outside of Richmond that I'd like to pull equity out of to out towards purchasing a primary home.

This would be our permanent home, in essence we would be the renters.

Permanent foundation, attached garage, paved driveway and connecting walkway, pitched roof, etc.

I have a scenario where I have found a manufactured home on a permanent foundation in an area where you own the land & have a very small HOA to pay for water, pool, parks, rec room etc.
