My deal is to offer a house seller-financed until the balloon is due in 5 years at which point, I either give the deed to title to record upon final payment or we're all done and they move on or renew - push the balloon out further - for a fee (non-applicable to the principal), on a 30 year fully amortized loan.

Software to get the price right etc.

However, I started in on the first application and have to select either single or multifamily.

I ended up receiving 50+ viewing requests and 15-20 filled applications for a single unit.If you are able to force appreciation/value addition, that might be a worthwhile project to undertake.

I personally just use a state specific application, verify everything on the application, then do a formal screening through rentprep.  

But so far I’ve only had 4 inquiries and 3 tours and 0 applications.

I have had some typical offers with wealth management companies and some software firms, however, I would love to be in real estate in any sort of capacity if I can.

The only problem it is still the beginning of the year and the new laws have not been really tested in CA as gar as number of applications and speed of approval. 

You have all the answers, call zoning ask for the local process, and what fees for the application are.

The best is a Real Estate Brokerage, since they will to the Application, Credit check, Background Check and Lease for one low fee.
