I had similar issue with my general contractor (Amit Shah of Rothwell Builders in Englewood, NJ) when we were building our house about 7 years ago.  

If it is only the credit check that is an issue then you should have the original lessee sign as a guarantor.

Even the ones that have the most professional set up can still have issues. 

We simple use a home warranty (2-10 or American Home Shield), which is ~$80/mo and offers services for most issues that renters have.  

She couldn't get the property sold because of the lease land and some title issues.

Might set yourself up for bigger issues down the road if you don't.

Unfortunately, I had to explain to him that he put hand-scraped hardwoods in a linoleum neighborhood.It can be emotional, when you're talking about your own home, but I would expect you are asking the question on Bigger Pockets because you want real estate advice.

I was asked about the issues with my credit and our compliance department waived any concerns.

I rented a house with sloping floors in college, and had no issues with it, but then again I didn't own the property!

Make sure you set up closing before the last day of your contract so if there are any issues you have time for your Closer to iron them out.
