I think it will give you tips as for getting started.If you want more information on actual flipping, I highly suggest you buy and read FLIP: How to Find, Fix, and Sell Houses for Profit.

Coinmac (or whatever they're called now -- google 'em) will put machines in there at no cost to you, service them, take the cash out, etc and mail you a check for your cut (they have different profit splits you can negotiate) .If you just have a small building, it's not likey worth the cost of doing a 'smart washer' that can take payment via venmo/paypal/applepay but they do exist. 

Of course the Seller has to understand that iBuyers are for-profit enterprises, they have administrative expenses and repair cost and want to make a profit at the end.

Or should I just buy a decent single family home and then sell it in two years and use the profit to buy a nicer duplex in the area I would really like to be in?

How should I split up the profits from a deal where I bring the deal and will manage the property and my partner will bring the money?

Alternately you could sell them one at a time and reinvest the profits from each into multiple properties. $200K would buy you 4 or 5 - $200K properties with 20% down.

However, we would all still like to have an equal split of profits and costs after the purchase. 

If the residents like the properties, it shows up in $$$ in potential profit and cash flow.

Personally, if I had to wait until you were profitable running a B&B, which you haven't done before, I wouldn't take the deal.

After we get rid of mortgage insurance our remaining gross profit will be right around $270/month.
