Of course you end buyer won't be happy and may have grounds for litigation against you if your sale contract didn't contain the proper contingencies. 2.  

Tee hee  Only raised the rent $15 dollars with old tenants in 6 years...you'd think they'd be grateful...honestly they will not find a better place than mine...free garages (2), attic and huge basement for storage...:) they had it good ;) they screwed up...i cannot continue to be a door mat...

I french drained the runoff to graded ground to further remove the water from the property.  

I disagree Maggie. back in the day when we didn't back ground check and a tenant fell behind I would offer them some money (not as much as the rent) to be moved out by a certain date and the place had to be broom cleaned to my satisfaction.

I love playing with third party APIs at work,  At home I have been busy trying to get the Real Estate business off the ground and I have been having to resist the build vs buy thing that devs love to do.

I'll be more specific with a little back ground.  

However, if a borrower told me they had concerns about their ability to pay, I'd probably decline the application on those grounds. 

The police and the LTB do not care that tenants smoke pot.Tenants may not withhold rent, this is illegalYou have no grounds to successfully evict.

I think it would be safest if I had a partner with boots on the ground so to speak rather than relying completely on a management company to oversee my investment.

I am very gratefully that within the article you provided an exit strategy for us genius that do what I just did.
