I've read BiggerPockets' Real Estate Investing book and am particularly interested in the house hacking strategy, as I'd like to move out of my current living situation.Our main dilemma is choosing between a single-family home (renting out one room to a close friend) or a multifamily property like a duplex or triplex.

Quote from @Havital Miltz: I do not know that if someone is in the hospital you can force them to close, I am not an attorney, but I doubt any court will find in your favor, closings do not always happen exactly on the day that is planned, even if everyone is healthy and well, the wholesaler here is not the reason for the delay so I am not sure what exactly you can sue him/her for, they are also being held up due to the seller not being wellJust give the person some time to get out of the hospital, closing will probably not happen the very next day either, this is really extenuating circumstance. 

Ask questions to find out about their reasons for selling, desired next steps (i.e. relocation, 1031 exchange, etc.), and anything else that is important to them.Ask follow-up questions to dig deeper and learn more (without being too intrusive) then jot down any relevant notes so that you can reference them down the line during your follow-up calls.

If the agent is not working out for whatever reason, cut the tie and move on. 

Not always the case but more times than not, this is the reason. 

I'd done some reading in the past and thought a few of the main Canadian banks had such specialty trust divisions that could help you with plan setup.As for finding investments, networking with other investors, real estate agents, etc. is the way to go.Brian, from what I've heard is that CAN banks  make it extremely difficult to setup. 

Interesting product, I am sure there is a reason why others are not doing it. 

Mainly the "self sufficiency test". 

Compared to other towns in Oklahoma.There is also an army base in lawton which helps keep the population high and another reason why the rental demand is high out there!

Reason is a Heloc generally carries a higher rate on a shorter term and "Can Never" be used as an "Asset, or for PITI reserves" which are both required when you buy an investment property.
