I’m also unsure about selling a manufactured home to use the profits for a down payment on a multi. 

Are you looking for small multifamily (2-4 units) or something larger (5+ units)?

sharing of revenue profits or lossessharing of capital gains or lossesis any payment to be made to either other than as share of profits, eg for ongoing serviceswill the participants be operating a ‘salary/dividend split’ – ie taking their month by month requirements by way of low salary, balance as dividends?

And on that note, working with a realtor - pros/cons (aside from commission cutting into profits). 2) I would love to meet with an experienced contractor about rehabs.

I am realizing  $300,000 from the sale ($100,000 profit).

I see a $20,000 profit. 

If it's a larger organization, feel free to inquire about their different staff qualifications.2.

It may only make a modest profit but it requires very little of my time, is a great place for my daughter to learn and grow, and provides a great benefit for our community. 

(this is also only true for my smaller houses; I don't allow it at my larger house, as my housekeeper needs the full turnaround time there)I find the charge (it's only $10/hour) prevents frivolous requests.  

The house didn’t need much work just some paint and flooring and will generate a little over $300/month profit after expenses.
