What numbers should I be aiming for?  

It’s always about the numbers.

After taking out all estimated settlement costs, carrying costs, profit expectations, rehab costs w/contingency the number at the end is what I can pay for the "shell". 

Best of luck

They have a lean on the property and owe more than what it's worth.Can someone help me run numbers to see if it's even worth it?

Everyone talks about the excitement of the refinance — pulling cash out, locking in new terms, and getting ready to repeat the process.But here’s what I’ve seen a lot of investors forget:What happens after the refi matters just as much as before it.Once you refinance, your numbers change — your basis, your loan interest, and your depreciation schedule.Most people never revisit their books or update their records after closing, and it slowly creates a mess.You’d be surprised how often investors forget to:Recalculate depreciation based on new cost basisAdjust their loan amortization and interest deductionsTrack how much cash was actually pulled out vs. reinvestedThose little details might not seem important now, but they can cause major confusion (and extra taxes) down the line — especially when you go to sell or refinance again.The BRRRR method works beautifully if your backend systems stay clean.So when the refi funds hit, take a breather, update your records, and make sure your financials tell the full story.That’s how you stay scalable, organized, and audit-proof.Curious — how do you stay on top of your numbers after the refinance?

Your general requests are going to get one of the following types of responses:1) General response2) Someone sharing what they know, which may not be right or even all the facts3) Someone trying to sell you something4) Someone trying to take advantage of your ignorance and naiveteGood luck.

What struggles did you incur with contractors prior to locating a good team of GC?

Leverage the banks , rehab, rent them and m refi to recoup a portion of what you spent if the ARV makes sense. 

Quote from @Tricia York: I would really suggest you get an estimate from a licensed contractor to really know what numbers you are at for the C remodel.
