I feel maintaining your properties correctly and being decent to your tenants is the best preventative measure we as landlords can take next to LLCs, insurance, and umbrella policies.

I'm in Alberta, so ASC has rules around what's allowed and what isn't (mainly aimed at protecting the public/investors).

There is no appreciation beyond that like you have in real estate, but it is the easy answer to your question at the moment… and inversely related to real estate, so as interest rates go down on savings, real estate affordability will go up by the same measure (more or less). 

Many investors use a general rule of thumb for midterm rentals that they should earn about 50% more in rents than an equivalent long-term rental (whereas short-term rentals should earn double or 100% more than if the property was utilized as a long-term rental).However, for DSCR lenders, change can be slow and challenging, and many lenders prefer and require more precise qualification measures than rules of thumb.

It's worth the $1k or so to take the correct measures.

I was excited when i first saw the properties and have been waiting in the wings ever since hoping it wouldn’t go through as I can’t find anything else quite like it and the aim is I will be living in 1 and house hacking.

Strategically, I aim to fit into as many development exemptions as possible. 

I asked for measurements to arrange the replacement, but they took two weeks to respond.

However, without bug control measures, they can get out of control. 

You should then answer any questions that come up on these forums and aim to add value to the poster and the BP community at large.All the best!
