Marketing on facebook for buyers and getting leads BUT

[Francisco Milan]

Marketing leads via forms and acquiring their contact info id say aout of 15 leads 3-4 answer and even go see the list of new builds I have them go see but not converting what can I do different to close these leads ? 

Should I meet them in person at the new builds ? or in my office ? 

I do ask them I can go with them but they say they are fine they will go see them by themselves then after they go they will think about it, my question is what would you do to close these leads ? 

Also most of the other leads dont reply back not sure why I am thinking of sending personalized video text
