The one guy I spoke with said they make money only when they sell to potential investors and they only sell new construction homes that are usually pre-leased to buyers (currently they are building in Texas state and Missouri State).

There will be less buyers to compete with => better price for you!

PMC is the professional that will have the most alignment with your goals - agents, lenders, inspectors, etc., are ONLY transaction based.A PMC has to deal with your property, tenants & maintenance EVERY DAY until you sell or terminate them.A great PMC can provide contractors and also check out properties for you. 

PM me and I can get you in touchwith some Wholesalers or Investor-friendly agents around Houston :) 

I am an agent so negotiated for myself.

From investor friendly agents, lenders, escrow companies, anyone for a new wholesaler and soon investor. 

My current insurance agent only deal with residential insurance companies.

To get those hours, maybe turn one or two into medium term rentals (you want the average stays to be over 7 days so they don't fall into STR status) which would give her more to do, particularly in the first year of furnishing them and getting everything set up.Alternatively, she maybe she could manage the properties but also get her RE license and try to sell a house or two a year - go to lots of open houses or run them for other agents?

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

As far as ARV I would find an agent who works with investors to work with you.
