Can someone explain the details of selling a house to a child?

Your mortgage has nothing to do with your taxes.Here is a very rough starting point, however the actual calculation will involve more details:1.

I would think their loan documents give them the right to control the property after the original owner dies - regardless of who is living there (although I have no direct knowledge of the laws where you live).There are details we don't know here... like if you want the house for sentimental reasons, or because you see the value between what it's worth on the market today and what the reverse mortgage company wants for it?  

I’m hoping that once I do have enough saved I can buy the second property and continue house hacking.Something like this: https://www.realtor.com/realestateandhomes-detail/2574-W-Fai...? 

The cost of PM here is between 20 - 30 % and frankly, while they can drive occupancy, they often have lower rates and less attention to detail (I worked with one when I transitioned a new property that was previously PM managed).

Have you obtained any detailed cost/benefit analysis quote?

Franklin Home Store and Vacasa are 2 local ones I found with a quick google search and I have no idea what they charge.If you want to consider the self-managing route, DM me and I can walk through the details.

The details of the incident remain unclear, but they intentionally granted access to someone who subsequently stole major appliances.

You would need to do a detailed write up of both you and your brothers situation to get any useful info from here.  

I’ve come across details regarding the Prohibition on the Purchase of Residential Property by Non-Canadians Act, and it seems there are exceptions for buyers with a valid work permit or for properties outside Census Metropolitan Areas (CMA) or Census Agglomerations (CA).Do you know if certain types of work permits are more favorable for this purpose?
