Unless you have a reason to worry...I wouldn't.
About a month before buying SSR I resigned from a job that I held for almost 12 years. I am now Self- Employed. DW only works part-time and we have two kids, two cars, mortgage, etc.
Obviously we woudln't be getting into
DVC if I had concerns about our financial future. Yet on the financing application all of the above was spelled-out in black and white, and I have no prior year tax records to document my self-employed income.
I took the extra step of including a one-page written summary that gave details on my situation and some income estimates. I then insisted on being pre-approved before sending back all of the signed forms. A couple of days after I faxed all of the info to DVC, the head of their financing department called me and practically laughed at me on the phone (probably due to my thoroughness) and said that we had been approved.
If credit history is a problem DVC will often ask people to put 20% down instead of 10%, but it sounds like you're doing that anyway. The fact is that if you default on your DVC payments, the points revert back to DVC. So they have little reason not to approve people after getting 10-20% down.
