Your statement does more harm than good.Unfortunately, your statement is blatantly wrong.

Given the impact rent control can have on new investments and investor interests, is it a necessary "evil" to protect the interests of the current renter base or is it causing more harm then good?

No harm in that.

I was an investor before I was and agent, so there is not much substance to your assumptions.

I felt they would argue a lesser period of time wouldnt allow them the time needed to find a place and I didn't want to create additional conflict in fear they would harm our property.

We don’t know any PMCs to recommend in the area mentioned, but since selecting the wrong PMC is usually more harmful than selecting a bad tenant, you might want to read our series about “How to Screen a PMC Better than a Tenant”:https://www.biggerpockets.com/member-blogs/3094/91877-how-to-screen-a-pmc-better-than-a-tenant-part-1-services-and-processesWe recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.

It doesn't sound to me like you're a professional property manager anyway - you just look after your own units - and unless you think there's a chance your friend might file a complaint against you, I really don't see the harm if it's one unit.

Although if there is other work going on at the house, you might consider changing it to avoid making another mess down the road, because in my experience old galvanized pipe eventually fills in with hardened substance and clogs.

In case of a multi-member LLC, showing that another member would be harmed by the forclosure may help to avoid this judgment.

I wanted to ask you because you were a retail home buyer.The true cost to me was the house you should have bought, but glad market appreciation covered your later purchase.The next time you hear an agent say 'no harm in getting an agent, it's free/No cost to you' you know better.
