@Charles Kennedy That's the biggest missing piece for me. 

While Airbnb is the biggest, look at home away which owns vrbo and is the second biggest site, and look at TripAdvisor rentals which is gaining a lot of ground on the others.

I have also begun to "pet proof" switching out carpets with the vinyl plank flooring, with carpets being the biggest issues with pets, second biggest issue would be chewing/scratching doors/trim. 

hi @Alex Russo my biggest bone of contention is that depending on what kind of listing agreement the seller has signed you may be encouraging them to break that contract which could end up causing them to pay a commission when it sells regardless of who procures the buyer.

Funding my first deal has been my biggest hurdle, as I am trying to come up with some creative ways to do so.

I am no lawyer or CPA, so don't believe a word I say and check it with professionals and people who have done it first (all I wrote below is taken from reading, so just assume I don't know what I am talking about ;-)), but my understanding is:- the biggest challenge is the due on sale clause (that gives the bank the right to charge the balance on sale).

I would say the biggest advantage would be if you could have your kids rent the rooms of the house out!

The biggest things that vary property to property are insurance, taxes, and utilities. 

I like  (and so will your future partners) that you have "skin in the game", that is probably your biggest selling point...and yes solicitation of partnership has every bit to do with sales as marketing a home on the MLS.

The biggest hurdle to overcome is clearly the start-up capital needed to get off the ground.
