You just have to weigh the risks and choose whichever you are confident with.

While it is most common for SFH lawns to be tenant-responsibility, we are offering a weekly mowing service for $100/mo due to being such a large lot, if applicant/tenant so chooses. 

You would need to choose between what is more important.... owning the listing or owning a STR that is dominating the market it's located in, by maximizing the tools available to manage the property.

Hi BP community, which one would you advise to be the next move for financing of next investment property, given the following options:

Airbnb has several options to choose from (Flexible, Moderate, Firm, Strict and Super Strict). 

Most importantly, choose a market that aligns with your goals!

But, if you choose to buy on your own then yes you can ask for financials directly from the seller.

Not as many “qualified” tenants to choose from.

I think an issue you will run into is how many Canadians choose to invest in the U.S. and therefore us the U.S. tools.

However, you are somewhat at the mercy of what the syndicator chooses to invest.
