Are you providing cable and high speed internet, security system, cleaning service etc?

@Ferrode Josephyes, it's in part it's because interest rates are so high. 

But, also as mentioned above, maybe the price is too high and doesn't make sense for investor buyers.

I have started analyze the deal and am still working on the details. monthly costs are roughly $1300Potential income is between 8k-9k dependingcurrently only 1 lot active at 950/mnth9 others with mobile homes in need of repair - cost of rehab of all units could be up to 100klot rent would go from 300-400 per without homes in this area seems like a pretty high upside and not very low downside to the deal.

I found a triplex with 2 long term tenants (5+ years) who I've met and kept their units in great condition, though they are in the units that are not renovated and in turn not paying as high of rent.

Yes NH can be competitive, especially in highly desirable towns like the ones you’ve listed.

@Ashley UndercufflerI highly recommend Andrew Hoek with Dewitt Law.

I recommend CA residents look at Reno, Nevada because of the proximity, landlord friendly, low property taxes, and influx of high wage jobs and strong appreciation. 

First I found it to show low rates, now I'm seeing them high.  

In addition, if anyone has spreadsheets or services they highly recommend for beginners.
