Here, properties are assigned value based on their last selling price, improvements made & (assumed) appreciation.

I find that providing a good product, with quick service when a maintenance request comes in and a sense of respect really goes far with these type of people. 20-30% cap rates with low stress are possible in these areas.

I'm concerned that if I improve the properties and plan to sell them in the future that the title may never be able to be clean enough to sell to the general public due to the tax sale.  

You could also ask the bookkeeper which CPA does he/she collaborate with and then verify the competence level with with the CPA.If you are concerned about the safety of your financial documents, most cloud based accountants use software (Quickbooks, file sharing services, etc) with bank-level encryption. 

Furthermore, water rights are very expensive in the front range, and regardless of transportation improvements, you are still going to have to buy the rights and then build the infrastructure to pipe water into all that space we have to the East. 

But don't fret it, the commissions are low, you have to do a lot free property management services, sometimes out of pocket hundreds of dollars waiting to get reimbursed, etc.

He does all my HVAC and now lots of my investor friend's service as well. 

Use an RMLO and loan servicing. 

We probably put too much into improving the properties but I prefer to have a safe house to rent and one that can attract a better tenant, and so far we're 2 for 2.
