You can build the tool yourself but it will take time. 

You can use this property to hedge any others that you add that may only cover themselves, or require supplement until they are paid off.HOWEVER, if you have decided that your goal is to use Real Estate as a stepping stone to build wealth by upgrading the property you hold each time (condo to house, house to 4-plex, 4-plex to 8 unit, etc) then I think you are right to sell now while you think the property is at the top of it's appreciation.It will be hard for anyone on BP to tell you what to do as we don't know your goal.You are right. 

Say, I have a potential client that has asked me to value a 7 unit apartment building.

.: I recommend networking and building relationships first.

I don't currently have any investment properties, but will likely work with a turn-key property managment in the Memphis/Little Rock area.My goal is to build a good cash-flow portfolio to ease into retirement. 

local PM here - I would master underwriting and build out your network.

I’ll definitely make that a priority as I build my team.I also appreciate your point about using different contractors based on the scope of work.

Be patient, take action when you're ready, and don't let fear hold you back—start small, learn as you go, and build momentum over time.Good luck!

we underwrite 10% land cost to finished build value.

@Jason Weidmannit's only solid if:1) you pick a market that you can go to in person and build a team first, and 2) you recognize that RE is a long-term investment, and you may have to wait 5-10 years, or longer, before seeing ANY return.
