My credit is in good shape.

I’ve heard of rent credit but lookin for other ideas as well!

Then I had to in detail explain how this wasn't a credit card....

Go to your local banks and credit unions.

When I was in college I was pretty irresponsible with my credit card.

There are not as many comps and it really depends on what is going on in the business world (tax credit wise, etc. ) to determine value unlike residential space where there is a general rule of thumb for the hot and off-peak market as well as a ton of comps for value. 

I have spent the last year working two jobs to save money and at the same time improve my credit.

Both are obviously terrible. 

Do you do background check and credit check also?

If so then you may be able to get 90% loan to cost depending on experience, credit score, loan amount etc...
