I also feel that the knowledge I gain from doing investing benefits my buyer/seller clients.

My PM has advised me that they have a different client who has successfully fought the appraisal, but it took about 3 years, and probably cost a fortune in legal fees. 

@Justin Feldstein this is primarily what we do for our clients. 

Second, your PM should be providing you with an analysis of market rent, they have access to what their other clients in the area are currently charging.Once you have a solid market rent, your PM should let you decide how much to raise rent, unless you want to hand that over to them. 

Neither does it make one a charity or a tenant advocate to recognise that it is in a business's best interest to retain it's customers so routinely threatening to fire them is probably not the best client retention strategy.To your specific question.

As agents, we can't access the exchange directly but when we rate up the house in a particular company we run reports before finalizing the sale.I usually recommend to my clients that they ask the current owners if they have had any claims in the past 5 years and what happened.  

I have worked in the 1031 space doing commercial replacement properties for about 12, but am now looking to set up a QI as per requests of a lot of my clients.

I have a client from Denver and their sweet spot is $150-$200k for duplexes or tri-plexes.

We have many thousands of clients holding rental property in their IRA accounts who are very pleased and getting good results. 

I always tell my clients however, if you are considering doing a transaction that you are uncertain would be in violations to the rules, simply ask.
