If you are keeping them then they have proven themselves and in return if they stay they are happy with you as a landlord.

A tried and true, proven model for scaling lots of passive income is to first have an active income funnel driving cash into income property. 

Since the federal law does NOT provide specific guidelines for service dogs and "teams", there's no way that local communities can try to implement any rules that federal law doesn't recognize at all.@ Calvin Ozanick, you can NOT request documentation "for the animal in question" because under federal law, there IS NO documentation required.  

No proven track record, living on their own for the first time, immature, bills being paid by mom and dad or borrowed funds, etc.

@Sheena Lee My tenants do payroll deduction or deposit at a kiosk...I've never had a problem with issuing the account numbers...My bank card just got cancelled because my Amazon Prime membership renewed and the bank didn't recognize it.

Again, I have no doubt that your intentions are above board, but you should recognize that this decision should have been made before the seller tied up the property under contract with you in good faith that the agreement would be honored, and I would suggest that the risks of your understandable oversight should be borne by you, and not by the seller through a renegotiation of terms this far into the process.

If you're buying it to only hold for a short time for the developer then a 1031 isn't appropriate for you so . you need to be ready to recognize a short term gain and pay tax on that.

I have a complex financial picture with RRSPs in Canada, RI in Canada, IRA/401k and other stocks/bonds in the US, vacation rental US,.. while I have confidence in my ability I also recognize that there are limits to my knowledge and speed at which I can learn (e.g. tax implications in two countries, ugh!).

This allows you to defer recognizing the income by transferring your basis to the new property or properties.
