that we’ve learned in our 24 years, managing almost 700 doors across the Metro Detroit area, including almost 100 S8 leases:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

I am looking to purchase a fix and flip in Daytona Beach, Fl.

Seriously, it's important.And as mentioned above, the amount of rent you receive on multi-family properties is based on 12 month rental comps.  

If the answer is yes, then it's a no brainer to make minimum payments on your 2.8% interest rate mortgage, and use the funds that you would have paid extra to pay it down faster, to either invest in more real estate, the market, or anywhere else where you can get a ROI > 2.8%.If the answer is no, then feel free to aggressively pay it down as fast as possible, to become debt-free faster, and just have a large amount of money in savings or to splurge with.The bottom line is that your 2.8% mortgage is GOOD debt.

I don't think Im paying my bookeepeer an outrageous amount, although with economies of scale (I have one commercial insurance plan, commerical portfolio loan from a single bank, one bank account, etc) it probably doesn't take the Bookeeper 3x to do my books compared to yours. 

Any amount you purchase less than you sell. 

It's great to have you with us.. do you think you'll focus more on fix-and-flips or buy-and-holds?

Remind them , how they felt back in July and how your deal edges against the amount of cash pumped into the economy (inflation). 

The other contractors that I have worked with gave me a full scope with detailed line items of what will be fixed, how much the labor is and how much the material is going to be.

Base the payment amount so you're in that range.
