So what happens is the buyers broker pulls double duty making one side of a commission and it can also sometimes put them in an implied agency position with the seller which can be dangerous.

Tenants in place should always require an estopell to prevent this. no legal advice should be implied just from my experiences.

There is never an implied POA so unless you purposefully entered into one, even limited,  there is not one.  

Just curious, was there a clause in your lease agreeing that the tenant could make alterations and repairs without your consent or was this an implied agreement? 

I would never imply that I know how to operate in another market.When you say there are not that many investors, and there are a lot of agents, I would consider that an opportunity. 

Regarding your first point, my goal was on acquiring my first property for a couple of reasons: 1) it implies I have successfully found, offered, closed on a property which encompasses a large number of critical skills in this business, and 2) it seems to me that closing on the first deal forces you to “make it happen” or, in another way of saying, taking the property and generating profit. 

If a listing agent calls you, he implies he wants to rep you.

Hi everyone,My property has a cell phone tower on its roof, and I just received a letter from the carrier saying they've decommissioned some of their microwaves, and that they want us to reduce rent in light of this usage change.There's an implied threat of terminating the lease ("<carrier> will similarly consider this site's viability and continue to evaluate alternatives").Now, I assume they'd have to at least stick around for the next several years until the end of the current arm of our lease, but I do enjoy the stability of having a much longer term lease with them.So... is this just a bluff, to shake out people who are easy?

In most states, this is an implied agreement and you need to follow the same laws you would as a landlord evicting a tenant.Since you cannot be sure that they have left, then notice should be given.

A ton of questions, especially if they imply you are a newbie may be a turn off.Good luck - Ned
