@Joe Baier and I would be a little concerned about your projected rents. You are looking at more than doubling the rents that are currently being collected. Now, I know you are looking to rehab, which will help get the higher rents, but I'm not sure I completely agree that you will be able to get those numbers just based on what they are renting for now. I would caution that though HUD may have a market rent price for the City of Norfolk, there is a very drastic difference based on the actual location in the city. Section 8 may be an option as their vouchers are less concerned with specific locations in the city.
Another point I want to bring up is your equity position. Yes, you have equity going in, but you also have $120k in renovation costs; what is your expected ARV and equity position after you spend the $120k, and does that $120k take into account the holding costs to do those renovations?
As others have said, if you're going the SUB2 route, I think you should have some really clear conversations with the seller. I would personally have a backup plan in place if the notes are called or anything goes south with the Mortgage companies.
Feel free to reach out if you want to talk. I would definitely get really solid on your expected rent numbers before you pull the trigger.
