Which refinancing route would you take?

[Casey Lance]

A lot to explain here, so I will try to make it short and easy.  I currently own 2.5 acres with a covered extended stay RV park.  I owe 47K on the property, and the value is slightly over 200k.  I want to add a final half acre that is available, to make this a full 3 acres and extend the park.  The cost of building the new section of park and buying the half acre is 100K. I have 30K in savings I could also dump into this myself.  Here are the options I have with the bank.

Finance all 150K for 10 years, giving me a monthly income of 3,300.

Finance all 150K for 20 years, giving me a monthly income of 3,800.

Or include 30K of my savings and

Finance 120K for 10 years, giving me a monthly income of 3,600.

Finance 120K for 20 years, giving me a monthly income of 4,100.

I also have an option of a private loan of 60K, include my 30K, and just finish paying it all off in the next 6 years.  This option would give me a monthly income of 2,700 per month.

All loans are around a similar interest rate it looks like. (5%)

Amounts are after utilities, taxes, and all other expenses.  After the park is paid in full, I will have a monthly income of 5200 per month at full capacity (which it has stayed at for the 3 years since I built it).

The biggest deciding factor among these options are my lifestyle.  I am trying to travel most of the year and live mainly off the income from this property.  Part of me wants to dump all my savings into this, go with a shorter term, and get it paid off faster, although I would have a lower income for the next 10 years.  But that 5200 would be closer down the road, especially with route of the private loan on 6 years.  The other part of me says keep all my savings for travel and emergencies, and finance all of it, and stretch it out for 20 years.  This would let me keep my savings, have around 4K a month income, but wouldn't see the 5200 until I was in my mid 50's.  

I am fairly new to the investing scene, and still learning.  I would like some opinions or things to consider from some experienced investors or whoever else may have advice on these options and idea.  Thanks!
