Hey  BP Folks,So I am looking to structure a deal with a family friend whose an active investor, where he would be providing $100K in startup capital. 

I am a man of faith, I believe in God, I believe Jesus is my Lord and Savior...and I believe we all have a purpose in the earth, to help each other be the best we can be in all areas of our lives.Sorry to be going off topic and rambling, but in a nut shell, this is who i am..be blessed

I am yet to be a landlord, but maybe structuring his payments with a different pay date to alleviate your headache.

They are underwritten as a commercial loan based on 1.20X DSCR and do not run into the FNMA 10 property or FHLMC 5 property cap and structured as a 25 year amortization with a 7 year adjust.   

I would like to learn how to set up the structure of flipping houses, so that I can be successful at it.

(Note I'm aware of several properties/owners that do this, but it does run afoul of the city's bylaws etc) and I think you end up with significant tenant management issues.Western University has a similar structure (Just with higher per bedroom prices for purchasing and same rent per room - which is offset by potential for more appreciation), however counterbalancing it is the fact that if you're close to the downtown you can also attract new grads/young professionals (which creates a more resilient rental property).Hopefully the above helps give you a better idea of student rentals in London.

How do I structure a seller financing deal?

Just make sure you structure it as a lease with an option rather than a lease purchase.  

@Adam E.As far as the structure of your arrangement, you have the opportunity to get in a deal or several deals with no money from you.

The tenant demographic for that type of rental is extreamly hard on what is a very flimsy structure.
