Buy it for $20k flip it to the 'client' for $40k & they do all the rehab on their dime, deal with landlord drama, manage it, unplug toilets at 2am & pay us 12-13% on the $40k.It's virtually a hands off 'passive income dream' with exponential cashflow & we've been doing it for 20+ years.

Which is where you should be making your money.Sorry if this sounded harsh. 

It must be a NE thing, because in IN we don't have anything like this.I would contact your attorney to find out how to handle this in the future, its my opinion that the 1st day I notice someone new living in the home I will find out was is going on and start playing hardball instantly be calling the police if I can't handle the situation with the tenants immediately.I have to believe that these new people are considered visitors in the eyes of the law if they are not on the lease and do not have permission from the landlord.Sorry to hear your experience, it think this proves that we have to act on these problems in a swift and harsh way when it starts.

You tenants save on postage and you don't have to worry about dealing with checks and drama like "I swear I mailed the check last week". 

Good relationships & stable rents go a long way to avoiding drama and unnecessary vacancies.  

Also, you should clarify this with your attorney, but I believe that as long as she can show residency, the eviction process in NH remains the same whether she is on the lease or not, and changing the locks on her outside of the legal system when you darn well know she lives there would be a VERY BAD IDEA. 3) Not to sound harsh, but you're a real estate investor; get an attorney.

I never know if somebody is being a drama queen or is upset with another tenant over something else entirely unrelated and is just trying to get them in trouble or what.  

Depending on your investment strategy and your tolerance for risk and/or drama, this property could be a nightmare, or it could be very lucrative.

I believe it cuts way down on drama for everyone to end everything as quickly and reasonably as possible.   

All three of my rentals are drama free, paid on time, and the property is clean.
