There are also some tax advantages to self-managing. 

They'll have the same issue with the next buyer and you can always come back in a few months and make them a much lower offer once the property has fallen out of contract a few times and they are extra motivated to sell.   

If you decide to sell and find an investment property with a greater cash flow potential.A 1031 exchange would allow you to indefinitely all of the tax and use it to your advantage to reinvest into larger nicer property/properties.

Payments $492 (interest, tax, insurance) currently owe $51K.

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.

My clients can "force appreciate" the value of the property by doing a quality rehab for a lower than market cost because they are very good at spotting "diamonds in the rough".

Rents may be high, but where are taxes and insurance.

I have made my own list of leads as well with some properties that I find vacant, probate, tax lien. but have only helped an out of state realtor on a deal a yr ago. and 2025 I would like to have the right people to go to with questions and or properties when I talk/find home owners that are willing to get rid of the property as well. 

I can do that through charging points, but since I'm getting it at a lower rate than you could as a consumer, I prefer to mark up the rate while still being lower than most others in the market.

No management costs as it would be self managed, and estimated property taxes by the average of the past few years.
