However, for any SFR and duplex, a residential lender will value the property based off the sales comp approach, just an FYI!

As if the foundation of the industry is assumed and we just jump in with myths and folklore flying right into storm without the instructor having a real education. 

I've recently had the roof replaced and fully updated the common areas.Here's a breakdown of the situation: The units are currently marketed as furnished rentals (cashflow well), and based on the current income of the 4 units I own, I anticipate that all 6 units combined will gross $182,400 annually.

While I am not based in KC I am familiar with the area investment-wise. 

For myself, I think my ultimate goal is to have an alternate cash flow to offset my dependence on a day job, which would allow me to choose a job I enjoy rather than have to find a job based on salary and ultimately allow me to travel with family more and enjoy life rather than stress about money.Thanks in advance and hope to connect and gain wisdom!

Maybe jump on some of those forums, like the FB page for Short Term Rentals Long Term Wealth for example and do a search for Evolve to see some of the comments.

I would base my decision on that.

My goal would be to buy, rehab, get up to market rents, refinance at a better rate.Three duplexes in Virginia:Property 1 (2 units - 2 bed 1 bath each)- Appraised Value: $245k- Mortgage Payoff - $183k- PITI: $1709.57 - Interest Rate: 9.25%- Total Current Rent: $600 (one unit is vacant)- Market Rent Based on HUD: $2986Property 2: (2 units - 2 bed 1 bath each)- Appraised Value: $270k- Mortgage Payoff - $202k- PITI: $1845.29- Interest Rate: 9.25%- Total Current Rent: $1450 - Market Rent Based on HUD: $2986Property 3: (2 units - First is 3 bed 1 bath, second is2 bed 1 bath)- Appraised Value: $263k- Mortgage Payoff - $190k- PITI: $1809.04- Interest Rate: 9.25%- Total Current Rent: $1500- Market Rent Based on HUD: $3572Other Factors:Total Current PITI is $5363.90Total Rent is $3550Tenants are all month to month with 1 unit vacantEquity After Deal: $197k (may be more as appraisals were done 1 year ago)Rehab costs to get market rent: $20k per unit or $120kLet me know your thoughts!

Should I sacrifice the cash flow and the great interest rate to jump start my real estate business?

A few other caveats: As mentioned by @Patti Robertson if you live out of state you must have an Arizona-based statutory agent.
