moving 401k to sdrira-company recommendations

Hello everyone,

I'm looking to move my 401k to a self directed ira to purchase str(vrbo's) and ltr properties.  I'm looking for recommendations from those of you who have done this as to what companies you have tried/and or moved to and why.  Are there some things i need to look out for when looking for a reputable company?  red flags or tips?  My funds are currently with a provider that doesn't allow re investments at all.  Can you let me know the average cost of doing so and what your experience has been.  thanks!
