This was a fun topic to read through... loving the different perspectives. You can tell who has been on the management side a lot of rental properties :) Its a tough gig.. So I wanted to comment on a few different aspects of the thread. I know Im late to the thread and there has already been some great comments. (my favorites are from Jay, James and Joel, btw).
I will say the communication is the absolute number one 'make it or break it' aspect of property management. I guess you could say that about any business but specifically in PM when dealing with the owners and tenants who purposely don't speak directly with each at all. So it sounds like they didn't pass that test. I mean at least you could get a hold of them before and after they re-leased the units.
The next thing is organization. Maybe they were to busy (aka: disorganized, under staffed, whatever else..) and forgot to attempt to raise rent. Well, if that was the case then they could have owned up to it and said "oops my fault it wont happen again" or something like that.
If the case was that they are truly market experts and they knew that raising the rent would cause a vacancy and therefore they have protected you from taking on that expense (which really is a strong possibility imo), then thats excellent, however it goes back to communication and lack there of. How will your clients know that you are doing them a favor if you don't tell them why you did what you did?
For us as a management company we absolutely advise against raising rent on existing, paying tenants that keep the unit nice. We actually lower rent by $25 after year one if they sign for an additional 2 year lease. And then we keep that rate going forward. Its also completely case by case as well... In some situations, areas improve, taxes go up and if one of our clients tells us to raise rent on the tenants then we have to take all things into consideration. If for example the area has improved (and taxes go up) then you have a justification for raising rent and its very possible that the tenant can see the value, agree and sign another lease at an increase.
But in the case that an owner wants to raise rent every year arbitrarily then we have every right as a management company to say that we aren't comfortable with it, and that we think it will cause vacancy, anger the tenant, etc. As a property management company its hard enough as it is to keep a good reputation with the tenants, and keep them happy with the condition of the property all the while making the owner happy with there numbers too. The management company should (IMO) have every right to make judgment calls like this, they just need to be clearly communicated. Keep in mind that most tenants aren't going to understand or care about inflation and your ROI. In fact a lot of times tenants are insulted by a rent increase and they actually think you want them to move. And yes like Jay said theres probably another competing rental across the street that was just renovated and its $25 less per month. A lot of markets are highly competitive like this. Think about all the hedge funds that bought from 2010 - 2015 that only need a 4 or 5 cap. Thats your competition.
This brings me to my next and final point... the notion that the owner of the property is "the boss" and that the property management company works for them.. Im calling shenanigans. Not true. This is not that type of relationship. This is more of an equal partnership. And guess what.. There is a 3rd party who's just as important. The tenant is just as big a part of this on going relationship as the owner or the manager. The tenants are PEOPLE, they are part of a community, they have a voice, they talk... They are the ones who obtain and send you MONEY. Very important role. I think its easy to forget when you don't have to deal with them directly.
Ok.. just fyi, that was not directed at anyone, just a rant. thanks for reading. :)
