Our leases make it explicitly clear that the co-signer has no tenancy rights, only financial responsibility should the tenant default on the lease. 

If not, you have a responsibility to attempt to limit your damages, which means showing the place right away.

I wrote the above for informational purposes.

Thanks for your responses!

I would specify in the lease that tenant is responsible for snow removal and de-icing of stairs and maybe provide a bucket of salt to them. 

With technology being so prevalent, is it impossible to find and close on a deal completely online while only using a friend to view the property (for due diligence purposes) in the area where the deal is located?

The search algorithms differ for each platform, but for Airbnb the main factors include response time to inquiries, instant book turned on, pricing, and reviews.As others have mentioned, I would look into other platforms/websites that focus on corporate rentals.

That would obviously cost you a lot more than your tax savings, and you would have to trust your 19 year old to be responsible with a huge sum of money.But to your actual question, your son would have to meet the 2 year ownership requirement in order to qualify for the capital gains exclusion on his portion of the house sale. 

I asked earlier if folks offer gifts to their tenants at the holidays or move in and I got mixed responses? 

It seemed like I was just getting a robot response or someone was copying and pasting standard replies.
