Tell them if they don't you'll have to proceed to the next step through the courts. 

Downpayment came from proceeds of a land flip bought at an online tax auction (**********).

I would suggest proceeding with caution, you want the freedom to change PM companies if one doesn't work out.

Any suggestions on how to proceed?

(Not really a surprise that CA makes life a little harder)The California Franchise Tax Board will require that you file a new form every single year (Form 3840) in which you detail what you did with your sale proceeds, where they are invested, and whether you ever recognized income from your sale or any subsequent sale.  

I'd like to sell one of my rentals and put the proceeds into stocks instead, but if the tax hit is too high, I'd do a 1031 exchange.  

The market when you purchased was a sellers market and right now it is not a sellers market and I know that this must be frustrating, as I have other sellers going through same issues Let me know how you would like to proceed.

It is your net cashflow divided by your net proceeds (minus realtor and other fees). 

After completing the online coursework, you'll need to take two tests before proceeding to the national and state tests, which mark the final phase of the journey.

The goal is to build a single family home but I have never done this before, and I am looking for some advice/tips on how to proceed.
