Keep saving as much as you can.

In the house that I hope to rent out to mid-term travelers there is a treadmill and I am thinking whether to keep it there. 

Therefore trying to get a bit creative with the financing.Positive cash flow will almost be impossible (as I'll have to probably take one bed away, and then build a bath and a kitchen) in what I've been finding, so Im trying to offset the mortgage as much as possible.Long term, ideally I get to keep it and the 2nd unit adds to the cash flow if I ever dont need it anymore. 

If you have a lease that is currently in place, you have to keep the terms the same until it ends and then have them sign a new lease with the new terms (give them the proper notice required).

Im from Edmonton, Canada and I have just recently closed on my 3 unit suite and want to keep my momentum going.

So, just like any other sale it allows them to require the mortgage be paid.However, it is very uncommon for them to do that as long as you keep paying the mortgage.

I have a great ISA , looking to keep her busy with convertible leads, thats a big reason I'm searching for a better lead source, even if they are 20-35% off the top;  there's barely any expired's in my market and the FSBO's are either toooo unrealistic with their pricing or if priced right they sell on their own due to lack of inventory.

Turns out he isn't ready to sell yet but may be soon so I told him if it's ok I'll keep mailing him and hopefully he'll let me know when he's ready.

I keep wondering about insurance, vacancy rates, if tenant selection is a bigger/ different factor, terms of the tenancy and differences in opex and capex? 

When you find those that are a good fit keep them!
