This is some information from my exchange company that I use for my clients that might be helpful for you. 

I offer a guarantee: if the client decides to sell the home down the road, I pay the referring agent a referral fee.They get paid, they know their client is going to a professional, and they know they'll get paid again if the client decides to sell.

@Anthony Warne: I do work with investors - in fact, I currently have two other out-of-state clients I'm working with. 

I recently looked at an investment property for one of my clients to learn that it had a section 8 tenant. 

The response does not form an attorney-client relationship.

Is your client is ok with giving out the address? 

I ask because they probably have a list of clients who are currently in default of their mortgage loan and are very close to going into pre-foreclosure.

When I sit down with clients I will always discuss (1) their personal assets, (2) what their current investments portfolio and other business ventures before discussing (3) their future goals.

@Ryan Riches99% of our clients who use accounting software do so via Quickbooks Online.

When I'm working with a client, I will be sure to pull the 5 most recent active, pending, and sold listings similar to my target property -- this way I can accurately gauge the pricing of that home.
