Brrrr Single Family to Duplex into Househack

[Brooke Spaulding]

Hello - I'm currently analyzing a single family foreclosure. Looking into converting to a duplex. In order to cover the purchase and rehab I'm planning on working with a hard money lender. Once rehab is complete I plan on renting out the larger unit and living in the smaller unit. What would I need to show to a bank to get a conventional loan? Basically I want to be confident I will be able to do a cash out refinance for as much as I could to pay the hard money loan back and have some to invest in next deal. Numbers are looking good for the deal as a whole but I haven't seemed to find as much information on the income proof/ getting maximum from refinance. 

From what I've read it would typically be 70% of ARV correct? At this point is it debt to income ratio where I could include the rental income for larger unit plus my W2? Thanks!
