If yes, how much and how long will it take? 

I believe you are in OR, one of my favorite States, but a long flight from pretty much everywhere.

You have the means to purchase and intend to offer owner financing (you) to the buyers of your lots.That sounds pretty straight forward as long as you are able to carry the loans and deal with any defaults.I don't have a background in raw land deals, so that's all I got.Thanks for the feedback and I will keep these things in mind as I move forward. 

I had to have Anderson re-do one of my LLC's from the other guys to save me money in annual state fees ..I look at it this way, as long as my business/investment income covers the costs I don't have a problem paying for reliable - worry free information and work.

Generally, the coverage of the policy will state; “The coverage of this policy shall continue in force as of Date of Policy in favor of an Insured after acquisition of the Title by an Insured or after conveyance by an Insured, but only so long as the Insured retains an estate or interest in the Land, or holds an obligation secured by a purchase money Mortgage given by a purchaser from the Insured, or only so long as the Insured shall have liability by reason of warranties in any transfer or conveyance of the Title.”

I have a mix of long term rentals and STRs and rent some of my STSs mid term in the off season so I am happy to share my thoughts and experiences with each strategy in this area.  

I recommend reading “Long-Distance Real Estate Investing: How to Buy, Rehab, and Manage Out-of-State Rental Properties” - I found it to be very helpful when I got started investing 2.5 years ago.

I'm born and raised in Houston and now work with a full service long-term rental management managing over 300 doors - all SF or MU (up to 4 unit).

Honestly, Tampa checks all the boxes for cash flow, appreciation, and long-term growth, so let me know if you need more specifics or help with a plan!

Is there more long term appreciation possible if you hold the units longer?
