The Class system (A, B, C) can vary by market, but here's my general breakdown:Class A: High-end, desirable neighborhoods.

I can tell you that being around new construction the past 12 years, I would say 1/4 of the projects we have been apart from residential to commercial will experience delays to MFGs out of stock, HOAs changing their specs, Cities changing their specs, Weather 2-3Xs budgeted rain delays, Subcontractor injuries and death.....Then Hurricane Harvey in Houston are.....WOAH  major delays...I have seen it.We are happy to be providing funding to DCGI's BTR community members, many have gotten their applications in already and look forward to helping the rest of yall accomplish your real estate goals. 

I haven’t seen any longer term studies done, only promotional info when the RE market was generally rising.  

I'm hopeful I'll be able to get my apartment back and not make the same mistakes again. 

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

I'd highly recommend Matt Scott and his services to those that are serious about raising money.Jorge

The seller said this is in a gentrified area so there's potential to rehab this effectively and get a high payout as shown in the last comp.

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.

we just managed to get ong to run all new lines and separate meters for our whole apartment complex at no cost to us. 

Having the contractor relationship in place to move quickly and provide a high quality renovation at a reasonable price.
