So I want purchase it as my first rental property it's going to need rennovations for sure not terrible shape just older rancher home.

I strongly recommend getting involved with your local REI meetup groups so you can work out your pitch with help from other landlords.I hope this doesn't come off the wrong way without tone or facial expressions behind it.

I do not think it would cost too much to tone it down howeverI got a $10k quote (minus fees) from an interior decorator recently to redesign.

These platforms include RentRedi, Stessa, Avail, Innago, Apartments.com (formerly Cozy), and TenantCloud.Pretty much every platform mentioned contains the features you are going to need.

I also doubt very seriously that any brokerage/custodian is going to allow this kind of loan with 401k assets; it's likely going to need to be a 401k general purpose loan, which is highly regulated (as someone else mentioned). 

I know it is expected that you will need to spend some money after someone moves out but I just didn't expect I was going to need to spend appx. $10k to get it rental-ready. 

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.

I don't think we are going to be able to come up with $50K before they're going to need to move and no, definitely no family members able to gift $50K. 

I know you said you don’t expect anything major on the properties soon, but I would take a careful look at what is most likely to need to be replaced soon and figure out how you would pay for that if it needed to be done tomorrow.
