As well, I have a small new construction condo project and having a really hard time finding funds for it.I did few flips using my own credit and conventional mortgage to finance it but there's certain limitations to these approach as well as rehab cost is not lender's concern.

@Jonathan Rosado, as for "the property will go under one of our names not both", conventional wisdom suggests that it should be in the name of the person who earns the most, for tax deductibility reasons.

He asked for 4% commission but charged us over 6% for no reason among other things. 

Of the top of my head there will be charges by the title company, an appraisal, lender fees...anything else?

After the rehab, I want to rent out the property and put conventional money on it, I assume the bank I get the new loan from would look at my debt to income ratio correct?

Caveat- I have not specifically looked into this and this is not intended to be relied upon as legal advice.The best person to ask would be the county prosecutor in charge of environmental issues, or someone at the county board of health. 

The conventional Lender may not loan on a property that needs work.Talk with some contractors and see if you can get a handle on rehab costs for your area.

Im being told I have to wait 6 months since it is a FF conventional loan.

They charge a set-up fee and a transfer fee for every payment.

We are wanting to buy homes and multifamily charge rent and use that as income for ministry purposes and also to house missionaries and people in need for and from the church.
