You are likely overpaying by $5,000.Broker fee of $3,000 and Processing Fees of $2,000 seem out of place...but then again, i never used a broker to get a loan so I am not sure about that.If the broker was able to get you an interest rate or loan product that you wouldn't be able to find on the open market...its high, but likely fair.if you are getting a loan product that you could have gotten by going to a normal bank...seems high and unnecessary. 

We've been able to rent properties pretty quickly, just as long as the rental rate is appropriate!

What you’re counting on is even a slow rate of appreciation, say equal to barely inflation, called it 2-3% being multiplied by 4 or 5X because you only put down 20-25%.

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 you do so - 100% of the cash converted is taxable.
