He already has his mortgage - so, a blemish on his credit really won't negatively impact him.All you could go after is his bank account and state tax refund:(

Thats with my cheap subs and me paying them cash using a GC this would be a $70k rehab and negative equity. 

I got a 2013 Toyota Corolla for $17k, so unfortunately, even if I trade it in I still have about $6-9k in negative equity on the car that I’ll still owe.

Your estimated first-year NOI is $29,040, but after loan payments, you're left with a negative cash flow of -$9,126 and a DSCR of 0.761, indicating the income doesn’t cover debt service.

Positive and negative forces will cancel each other out to some extent. 

The bottom line assumes that your overall cash flow will go up from acquiring this new asset, which existing property, when you leverage will have the smallest negative impact on your overall cash flow. 

If you want to discuss more you can always send me a private message but so far I don't see any negatives with purchasing the multi-family.

No, I'm not going to explain the concept here.

This creates a negative initial position.

Insurance rates stand to rise dramatically, so the question is "will the insurance rates go up enough see rentals go into negative cash-flow situations?"
