Instead of recommendations and professional advice from her I found myself with more questions than answers often times, and her newness and lack of confidence left me feeling like I couldn't trust her.I think you're already 4 steps ahead of her as you're here asking the questions and are engaged on the BP forums which in my opinion, besides having a great broker with seasoned agents to learn from in person, is the MOST important thing.

To provide some context, I work in my family's business, but my parents are getting older and are formulating an exit strategy that will have them out of the business within the next 5 years.

Days on Market is increasing steadily, driven by those older condos. 

For new investors, you can secure up to 90% of the ARV, and for seasoned investors, there are even opportunities for up to 100% financing, depending on the lender and the specifics of the deal.If you need any assistance or have more questions, I'm here to help.

I have seen older articles on these areas but wanted to get a more recent opinion.

In recently decades municipalities have passed lot minimums that render a huge number of the existing lots unbuildable, so they have had to accept grandfathering in a large number of the older lots.

This is how they kill older parks.
