I was mislead and should seek mediation to recover some or all of the earnest/hand/deposit money?

I'm going to reiterate what's already been mentioned above, but I'm going to actually give you examples of why it's relevant to you to find a U.S. tax professional.1 - You're going to need to file U.S. taxes once you have property down here, there's federal filings, state filings, and sometimes local filings too2 - Tons of tax treaties between the U.S. and Canada that are easy to miss and can cost you a lot of money (important one with rentals - effectively connected income - if the professional you talk to doesn't know what this is, run away)3 - The amount of days you spend in the U.S. needs to be tracked and if you go over a threshold, all of your worldwide income could be taxable by the U.S.4 - Selling real property means up to 15% of your sales proceeds might not be available to you for years (FIRPTA)5 - Lots of nuance at the state and local levels, which both want to take as much money from you as possibleMain takeaway here is that you should find a U.S. based tax person.

If not, ride out the 12 months with the hard money lender.People have to make good choices and not over extend themselves just for the sake of buying something they really can't afford or that doesn't make good cash flow.

On one hand the seller obviously wanted as much money as they could get.

Quote from @Jaycee Greene: Assuming you pay asking price, I'd estimate the down payment for something like that using a hard money loan (HML) would be around 40% of the purchase price and your monthly payment would be $2,600 with an interest rate in the low 7% range (probably need a 700+ credit score to get that).

I would love to explore the rest of the US - if I had the money.

I have a question and would really appreciate your input.I’ve done a couple of fix-and-flip projects in the past using hard money lenders, but I’ve noticed that their fees and interest rates significantly cut into my profits.

And I used all my rental mailbox money over the last 9 years since I first started investing to buy more and more.
