As mentioned before, stairs were broken, floors were moldy, etc. 

You mentioned you might be doing something like that.

There are more buyers for SF homes, but Multifamily properties typically cash flow better as you mentioned. 

Often times you will pay much more in taxes than if you pulled the money out, paid the taxes and penalty and then started investing in real estate.For example, with the financing you mentioned, the IRA must pay taxes on the portion of the profit earned by financing. 

People mentioned master lease so are they essentially arbitraging the unit?

Funny you should mention that.

The numbers you mention in your post are confusing - like $150k annual income from a rental property.  

Marie Poe...her account is deactivated, but a search may turn up some of her info if you search the name and someone mentioned her in their replies.

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 this is the case, would the original seller financing have to mention that the buyer (me) can re-sell the property at any time?
