A buyer should never feel(OR be made to feel) guilty when agent shows you property, whether it’s 1 or 51. You did not choose their job, they did.

Not all agents are Realtors. You can be represented by either.

I ALWAYS tell clients that virtually everything in real estate is negotiable. Although some things may be ‘standard’ there are blank lines and boxes to check on the purchase contract.
Most people don’t seem to grasp this.

One thing that I detest is the ‘loan contingency’
and most agents cannot explain what it really means.
I ALWAYS suggest trying to negotiate your loan contingency be removed AT FUNDING and not before.
There is an option on the contract for this.
It’s not always possible but understand that you are potentially putting your entire deposit at risk
when you lift the contingency and you have no control (or understanding) of if your loan will actually fund.
