Should I buy up as many cash flowing/appreciating properties for long term holds as possible to add doors to my portfolio (although, I haven't enjoyed being a landlord thus far...)?

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.

.)- Average days on market- Absorption rate- Historical data on rents and sale prices in the area- Population growth- Main economic drivers (industries, individual companies, etc.)- Crime stats... if you know specific zip codes/submarkets that you'd like to target, the best data will come from local precincts. - and more..I'd recommend remaining active not only here on BiggerPockets, but in other valuable RE investment networks that you can find - i.e. local meetups (meetup.com, eventbrite, BP local events). 

My goal is 25 doors in 5 years, my struggle right now is deciding to either go back to work and save up money to continue or come up with a way to leverage financing to stay afloat myself and stick with it, waking up everyday 100% dedicated to my real estate. 

Simple things like a branded email at your domain and a website can open a lot of doors.
