The 30 year gives you the added flexibility (and safety) of choosing your payment schedule as you go, at the expense of a slightly higher interest rate.

More of a safety-net in my eyes, in-case something unexpected happens or plans change before I move to the next property.

But what I really want is the freedom to be able to take risk like start my own business, get into a startup, etc. but have a basic safety net or backstop in place in case things don't work out.  

For many, certain real estate investments are a flight to safety versus alternatives. 

Hi, we have a 100 year old cottage on Webster Lake in Franklin New Hampshire under contract and need someone to look at the property with us to ensure its safety, viability and to do some work to it.Please let me know if you there is any body out there!

And the section 8 requirements I don't see what you are referring too because I know they do a yearly checkup but that's just for safety most things you won't have to worry about.

Secondly, if there is a larceny (or worse), you want a clear conscience (and no culpability) if you are ever asked by LE or courts whether you changed the locks or not.I know some people on here don't like them, but I have had good results with the Kwikset Smartkey system, which makes this a 30 second job.It's really a small price to pay for great return via goodwill and safety.

The inspector calls out the safety risk, but we have no idea who we should contact to fix it(we want to keep the trees if possible)?

Also, letting them know now that I expect the place to meet certain “cleanliness” standards for health and fire safety reasons.Anyone else have thoughts on this situation?

You'll have the safety of having earned equity and protecting it.
