I recommend you send notice earlier than required and by multiple avenues to verify receipt.

Would you like recommendations on resources or contracts?

But shoot me a PM, I got a few recommendations. 

I recommend renting it as a 4/4 and being clear about the set up. 

Any advice or recommendations would be greatly appreciated.

The best strategy I seem to have deployed so far was to contact all my current tenants and let them know I’d give them a cash referral fee of $250 for anyone they recommend to me that goes through the vetting process and successfully moves in.

I like to always recommend that you choose an agent who is also an investor maybe a few years ahead of where you want to be.

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

As you develop the park I would strongly recommend your homes be individually metered for water, sewer expense prorated and garbage paid by tenants via individual can service. 

Ask for their advice and maybe even something a little corny, like whether they’d be willing to write a letter of recommendation for your lender when the time comes.
