I use credit cards to generate a credit history. 

I have played the 0% balance transfer game for some larger inventory purchases in my retail biz and good old 0% balance promos at Home Depot (personal) and Sears have financed quite a few apartment renos too.With a long and stellar credit history It doesn't seem to impact my FICO4 & 8 too much but it will *crush* the vantage 3 score which penalizes HEAVILY those who actually USE their credit and I'm talking still less than 30% of available.

The problem Im running into is my work history.

I provide the Airbnb earnings report and history of bookings.

I need to get my grand daughter over here during Christmas and see if she can help me.

DUNS keeps a database of credit history on corporations.

I should add that I have a history with this GC.  

Verifying last 2 years of rental history very important!

Before I bought it I was buying real estate giving myself and my daughter something to do, my lily girl (Alice kate) was disabled and a single father it gave us something to look forward to every day rehabbing apartments, I started doing some research on turning a small complex into something for her and design it for her wheelchair in case something would ever happen to me, she would have her own place ,in my research I seen assisted living facilities and thought thats what she needs something with nurses. well I found this 4000sqft building and it was an ALF I made the owner an offer and bought it!
