BUT I do think you should verify the company first. 

Had a lady with pay stubs, someone posing as her supervisor verifying employment.

I would say though towards some of the questions regarding the FHA loan ask your lender and verify by asking more than 1 lender sometimes people don't get the info correct or are still using the laws from 20 years ago!

Definitely recommend using a contractor with the designation as a Certified 203k Contractor - 203kContractors.com Any contractor can say they do 203k's or like 203k's but maybe best to use one that has been educated on the 203k and had their 203k experience verified. 

Due diligence means you are doing ALL the research necessary to verify the investment is what you are expecting to purchase.

Have you verified their names with those on the lease(s)?

What are the best sites that you have found to find the best contractors in your area with past verified projects and reviews?

@Bob Romano trust but verify.

Three reasons: (1) the federal government is still in the driver's seat with Fannie Mae & Freddie Mac, so those mortgages will get deferred or worked out in some way; politicians got killed last time for the foreclosure rate, so they are not going to let it happen again and (2) the fundamental structure around loan origination is a million times better than it was in the run up to 2008; between 01 - 07 you did not need a license to originate a loan once Dodd-Frank passed and licensing became the standard a lot of bad loan officers got out of the business, and (3) Banks also tightened up their verification standards ( I know the standards are still relatively loose) but 4506T forms were not used between 01 - 07, so people lied about their income; after 2008, banks started to use 4506T forms to verify tax returns. 

RESIDENTIAL TENANCIESDo not rely on what others say without verifying for yourself.
