A big problem on the BP site when people ask for advice when dealing with Multifamily properties is not identifying which classification of multifamily they're seeking advice on.

On that note, what site and or public records entity should I be looking at and how much and what kind information is available there?

The problem with tax deeds is no one knows if the municipality properly served everyone to clear the title.

Code Section 40-10-74 says: If the mortgage or other instrument creating a lien under which a party seeks to redeem is duly recorded at the time of said tax sale, the said party shall, in addition to the time in this title specified, have the right to redeem said real estate sold, or any portion thereof covered by his mortgage or lien, at any time within one year from the date of written notice from the purchaser of his purchase of said lands at tax sale, served upon such party, and notice served upon either the original mortgagees or lienholders or their transferee of record, or their heirs, personal representatives or assigns shall be sufficient notice.

If they redtag you then you need to bring it to code with permit (70 West Hedding, planning dept).https://www.sccgov.org/sites/dpd/DocsForms/Documen...Sam ShuehCupertino, CA

The termination of utilities could give you reasonable belief that she’s abandoned the property, but you’d still need rent to be overdue by 14 days and to serve a Notice of Belief of Abandonment. 

As long as they are patient, licensed and willing to help you (and they should since there is a possible commission at the end of this rainbow).I would suggest starting with one of the national realtor sites (zillow, redfin, realtor.com, etc), search for multi-family properties all over your area, pick one (anyone that looks interesting) and call the agent to get details. 

there are multiple sites that various NH towns use. 

The representative informed me that because there was already a paid advertisement for that building on the site I was not allowed to post on my own and I had to contact the property managers for the building.Has anyone else had to experience this kind of runaround and hassle just to list on either of these sites?

Also factor in on-site coin  laundry bringing in another $150 a month and garages bringing in $150 a month.
