Can you Sell Properties when You're not with the buyer on Site?

<---------Down Payment Checks and Contracts)
I had recent transaction. Im selling a property sa tandang sora. I've shown the properties to more than 3 people and none of them put the down payment though expressed interest.

It was 8 am when someone called me that they wanted to see the property through his wife early in the morning the same day at 9am. woah! (im not a superwoman that can go in 1 hour from Molino Cavite- Tandang Sora Quezon City)

This is my philosophy about tripping when the

client says she/he will go to tripping follow his date and time if he/or she doesnt want to move it believe me take ups are most likely sure.

So I had no choice I called the owner of the house told her that someone is coming by this name ( at the back of my mind i was telling my self i hope the buyer or the seller will be loyal to me though both are just new people to me)

After the buyer told me that she'd visited the property, we had the negotiation luckily the owner has been loyal to me she told the buyer to negotiate about the price with me. and we closed the price and waiting when is the downpayment hay...thanks

The following day the buyer texted me that she's in the bank preparing the down payment wallah!!! deal closed.

I was not there during the tripping. but the secret is loyalty of both parties: even though we have written agreement of the seller still it can be messed out if the seller or the buyer was not loyal to me as broker.

the secret: loyalty - established credibility that makes them loyal to you. before the buyer went to the property i made sure that the buyer understands that i am the exclusive broker meaning the owner is selling that through me all the documentation and negotiation should be through me. And before the buyer go to the seller I made sure that i have written agreement and have initial contact with the seller and somehow established my credibility to her as a broker so somehow i have already earned her trust.

So the answer to the question is YES, you can sell properties even you are not there in the tripping. HOW? Establish Loyalty and Trust to both parties.
