Can this be done tax efficiently?

I guess what I would ask is, in what order should I approach these different individuals in order to maximize both efficiency and accuracy?

Also, is this a high efficiency HVAC system?

Just the way I have learned to do it efficiently. 

Also, how much of a factor is distance from the Dartmouth and Halifax downtown regions, when it comes to rent prices?

Some questions to ask (from @David Greene’s book “Long Distance Real Estate Investing”What experience they have managing rentals personally, how many doors their company manages, how long they have been in business, and what they feel their company’s strengths are, how they collect rent, how they enforce late fees, what systems they have in place to make things efficient, and how long they have worked for their current company.I hope this helps. 

It's much more efficient this way.

I let them go on for months, costing me thousands.But I learned and handle things much more efficiently these days. 

We have vetted the builder, walked through their factory, systems and processes and seen the final product rented in the market.

Maybe you will be better at estimating, or more efficient with the work.
