Due to his age, he is not interested in seller financing (due to the 15 year term) He is happy to help me in any way, and I plan on asking him to do a lease option on a couple houses.If I can structure it to where I net $100-200 a month, and have the option to buy in 1-3 years, that would be great for me.

The issue has to do with the age of the park.  

Age: within 15-20% of the same age as your subject property.Neighborhood: Comparables should be within the same neighborhood.

My father is getting up in age and I am calculating investments from this point forward with the idea that I will have money from my inheritance to work with.

Age, condition, and type of mechanicals.  

Now my kids have their own IUL  , locked in their insurability plus putting the power of compound to work for them at age 6 and 7.

Age of the park. 

It was at this point in my journey (around February whilst staying in Amsterdam) that I discovered a man called Samuel Leeds and his financial freedom challenge.Samuel is the one who showed me how working as a full time property investor can allow one to achieve financial freedom.

And again.This sounds like a deal I would do if I were your age BUT I would have done the deal at a cheaper price and do it with more units.

Whether it would be the better plan for them or not over the long term would be something to discuss.Since they are over age 59 1/2, they should be able to move any tax-deferred IRA or 401(k) type savings into such a plan via rollover, including from their current employer plan.
