Hi @Deepak Malhotra,Thanks for sharing your experience—there’s a lot to learn here!

Can I DM you to pick your brain on what you've learned over the years?

I’m here as a 51 year old newbie to real estate investing and wanting to learn as much as possible.  

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.

Moving from SFR to MF has its own learning curve without the development part.  

.), and anything else that is important to them.Ask follow-up questions to dig deeper and learn more (without being too intrusive) then jot down any relevant notes so that you can reference them down the line during your follow-up calls.

If you're running a fix & flip business, you'll eventually want to learn how to estimate repairs and independently prepare a scope of work.

You can easily do this on a spreadsheet and it will take less time to track than it would to find and learn a new software.

I have been binge listening to The Bigger Pockets podcast for the past few months and have learned a lot so far.
