I almost made the same ROOKIE mistake until I was warned by my banker.

He will take your money and you will be left with nothing or actually you'll be left with expense after expense and he'll be gone and no reply.you have been warned.

It can also help you with security and other issues.The other option is to notify the tenants and warn that the next fine will be split equally and passed on to all three tenants unless someone can identify the responsible party.

I'm not entirely sure where to start however I have been warned by some others that the city inspectors tend to look for violations which can greatly increase the scope of work.  

Just warning you most of it will be negative.

A fair contract will allow for no termination fees if the PMC failed to materially perform their duties after a 30-day warning.

Contact the upstairs neighbor and ask her to try and keep things quieter, but you also need to let the downstairs tenant know that this is normal in an up/down apartment building.In the future, you can help reduce these complaints by warning every applicant that noise travels in apartment buildings and they can expect to hear their neighbors.

But I want to warn people that it is not what you think it is.  

If you have a fixed rate mortgage, as you should, an increase in interest rate has no impact on anything with a hold property.Agreed, I said it because I was trying to warn those who use ARMs. 

We warn and warn and warn people about this and title company does and lender does, but somehow it doesn't sink in until they get the new bill in a year or two.
