Has anyone used Dwell financing successfully?

EDIT: The reason I've looked at the SFR or house-hacking option the most is because I feel the house-hacking will help provide me some experience and confidence in multiple fields I'm interested in (rehabbing, buy-and-hold) and a steady stream of income each month, and the SFR route will allow me to collect some in-the-near-future income that I can use to reinvest in more deals and expand quicker.

When you get into trouble is inflating or being overly optimistic about the expected cash flow streams of a new project and then underestimating the costs.All in costs go up and expected income goes down.

Having you RE license will give you addition revenue streams.

You can never have too many streams of revenue entering your bank account.

Here's a couple of posts on the subject that may give you a little insight into this industry.I personally am planning to jump into this industry with all fours in my geographical area as there are literally thousands of homes and properties with enough room to add "Additional Dwelling Units" on their properties.

A whole stream of events issues from the decision, raising in one's favor all manner of unforeseen incidents and meetings and material assistance, which no man could have dreamed would have come his way.

I want to start generating my own stream of income and wealth.

Lets just say 1200/yr  100/month..Per month = 775.40 x12 = $9,304.80 Yr.Now Calculate Rents:  1300 x 12 = 15,600Less Vacancy 7% = 1092Less Repairs  10% = 1560Less Capital Reserves 5%  = 780Total Estimated Net before servicing debt:  $12,168 YearDebt, Insurance service:                                  9,304.80 YrCash Flow                                                        2,863.20 YrCash to do this deal was:                                15,500.00So in this scenario for 15,500 you bought yourself an income stream of 2,863 What is that 18% on 15,500?  

Do you have a continuous stream of cash for this?
