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

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

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.

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

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

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. 

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.

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

From that point, some sort of banking engine would need to be involved that was sophisticated enough to handle and understand trivial to highly complicated financial transactions.In any case, it would be fascinating to a small niche of people (myself included) so not too likely to become a commercial success.

I know that it takes time to rank highly on Google.
