How to qualify a turn key rehabbing(and more...) company

[Allende Hernandez]

Hi there folks,

I bumped into a turn key RE company in the Orlando area that offered to manage everything, from finding, acquisition, to financing, to rehabbing and selling. They supposedly also do lots of new construction as well. 

I will meet then in person in the next few weeks because I am looking to invest in the area and being in Miami (3 hrs away) having such a resource seems very compelling. 

They have a brokerage firm as well so they will present me the deals, already inspected and with a firm rehabbing budget they guarantee will not change. If I agree, we move forward with everything else. They charge about 10-15% of the rehab costs for the management.

What are the things I need to be concerned about? What are the questions to ask? Tips if you have ever used one of these "all-in-one" companies will be greatly appreciated.

I tried googling them to find some reviews but didn't find a thing. 

Thank you all in advance!
