You can install an exterior security camera for the duration of her tenancy and the rehab with remote access.  

In New Brunswick application of the Residential Tenancies Act is a little more even handed.However, if you are planning for short term rentals (i.e. a duration <1-week), you may well find they are not governed by tenancy law, but are viewed as being hotelier and governed/licensed as would be a hotel.

My first set of renters stung me on this and didn't leave after their designated stay duration.

Purchased Price, rehab cost, rehab duration?

Initially, I didn’t care too much about the income as I was more focused on equity and be able fully pay off the property in considerably short duration.

So yes, 100%, persons should hunt NOT for cash-flow but for APPRECIAITION opportunities, where that appreciation has duration and deployment into operation, to monetize the appreciation, better known as "cash-flow". 

I think the best you can do is a 60/40 split of all revenue in favor of the owner with free maintenance/ repairs, with free leased machines for duration of contract.

If you’re not dead set on a specific closing date, you can write in that the seller can select duration “allowing for title search”.

Just so I am correct I believe i saw a one time payment etc which is only good for 12 months then monthly amounts for the duration of the partnership?

I had one group of tenants who literally stated that exhaling into their stupid bounty blower (look it up) should make it undetectable... again, they were stupid, they got told all of the above and I explained to them that the duration of their lease was their legal and financial responsibility even AFTER eviction and that I would garnish their wages to recoup that IF NEEDED or they could walk their cheech and chong butts out to the sidewalk like they were told to do the day we signed the lease agreement.
