Seller Finance + Rehab Loan??

[Darren Finan]

I'm currently under contract for a duplex with seller financing. Purchase price is 375,000, 5% down fist year IO amed over 15 yr at 4.5%. Pretty decent terms as this is my first seller finance. My question NOW is how do I fund the renovation?? It needs easy 100K worth of work, best estimate so far is coming in at 98K. So I'm looking to borrow 125K. But from where?? ARV for the property rehabbed is 750K-850K, so lots of equity to be made or tapped into. What's the best route? Commercial line of credit secured against the property is what I'm currently looking at. 4.25 4 yr balloon IO. My ideal scenario is to renovate for 3-4 months then refi into a 30yr product.
