3) Should I skip this step, and go right to larger multi-family units, partnering with other investors?

If it ever changed, I would just do it myself to save costs, but don't see it being something that will come up in the near future. 

Anyone ever try the app plowz & mowz?

Has anyone ever had 1 tenant forcefully removed from a property while another tenant stays and a new lease is created?

I'm always last priority or maybe they are running out of money, but for whatever reason, their communication, organization, and follow through are the worst I have ever experienced in business.

You will have to walk through your own detailed analysis and get back up documentation (e.g. contracts, bills) to confirm everything possible.A larger scale owner probably used more 'sophisticated' systems.

Has anyone ever rented to bob?"

They are going to look at how many debts you've had in the past, the nature of the debts, how long it took to pay them back, if you were ever late, chargeoffs, etc. 

There for if the seller wanted $200,000 for the property (renovated over 60-70%) - He would pay $6,000-$10,000 (3-5%) in realtor fees - Then who ever buys the house would pay $200,000 for the renovated house + $30,000 in HST (15% on PEI)?

One way or another, and if nothing else, someone has to evaluate the property as to the probable cost to bring it to an after-repair-value that matches the surrounding market's fair market value for comparable properties - before ever offering to buy it at "such a ridiculously low price" (as the seller will term your offer at first), let alone, before offering to sell it at "wholesale" to your buyer (i.e., so far below fair market price at retail that the repairs can be covered as well as your profit and the flipper's profit in its eventual retail sale -- or 'buy-and-hold-to-rent-out'er's profit before they would expect to get it rented -- plus the title search, closing, and any tax costs related to your purchase from the seller (usually split somehow) - and finally, the title search, closing, and any tax cost split with whoever buys it from you.Now, that someone could be you (you do trust you and your repair-estimate abilities, don't you?)
