I’m not sure what the property is  worth, whose positioned in first and what the condition of the property is, but consider leveling with the client using an attorney first. 

I know some of these clients have large investment goals but are just starting out like yourself.

If "No" and it has to be for 1 year and for everywhere, then walk away (unless it's mandatory).The agreement is designed to designate the buyer as a "client" vs. being just a "customer."

I'm currently in the middle of getting my Real Estate Agent license and hope to have it done by end of year.i was studying my Law of Contracts material and i came across the rule (537.11) that states that agents must use TREC promulgated forms in a transaction unless the license holder (me) is acting SOLELY as principal or the principal (client) requires use of another contract and/or one prepared by an attorney.  

@Don Carey My clients and I usually wish the Sellers well and tell them that, if they ever change their mind and want to take our offer, to give me a call and if we haven't already bought something else, we might be able to work out a deal. 2/3 of the time you never hear back from them, but sometimes you do.You know what you're willing to pay based upon your business model and stick to it.You as the Buyer have the right to offer what you are willing to pay.As the Seller, they have the same right to ask for what they want.Sometimes the parties come to agreement and sometimes they don't.You're not doing anything wrong.

They have their clients use quickbooks online for tracking the financial data. 

We had a client that the house was fine but after we had to go to court to get them out they trashed it on the way out.

It is for a 3BD (including master suite overlooking a lake), 3Bath, nice neighborhood.I'm trying to figure out the wear and tear I can expect from different prospective clients like:- Teenagers- Children- Boys vs. girls- Old vs. young- Extended family (e.g. grandma, mom, daughter in the house)- Other?

The listing agent is not the ultimate decision maker, their client, the bank, is.
