You can show proof of funds for a downpayment and anything that indicates you are financeable and/or if either you or your partner have any RE/ MHP experience as a start. Some areas deals might not make sense. Some are better than others. Dont confine yourself to a particular region if the numbers done work.
That being said, if you are going remote, make sure you understand what comes with that, the deal is worth it and supports it, is there a turnaround component and how much at mercy will you be of a manager and does the deal size support it.
One of the hard parts is trying to find deals. There is competition for buyers and established buyers might get first shot at a deal before other deals come up. You can network with others to see if you might be able to find a deal before it hits market or hopefully a brokers pocket listing.
Sounds like you are on a good path, just keep networking, check out those parks so you can really get a handle on valuation , what a good deal looks like and a bad deal looks like. Good luck
