I have recently been made aware that I get straight to business without really concerning myself for the sellers side of the story and when you have the sellers problems, goals, etc.

These are pretty much the replies I expected, but great to hear that I'm not the only one concerned with guest safety. 

Here’s what could be going on:✔ Legitimate Concern – Some tenants worry that HR inquiries might raise red flags with their employer, especially if they’re still in a probationary period.⚠ Fabricated Offer Letter or Pay Stubs – Unfortunately, fake employment documents are common, and verification through HR is one of the best ways to confirm legitimacy.⚠ Unstable Employment – They may have lost the job or never actually started, making verification impossible.⚠ Other Issues – They could be hiding something (evictions, unpaid rent history, or other financial instability).What You Can Do:✔ Ask for the official employment verification letter – Many HR departments provide standard verification letters upon request.✔ Verify pay stubs – Cross-check them with bank statements to confirm deposits match.✔ Call the employer directly – If HR is off-limits, ask for a manager’s contact instead.✔ Stick to a Consistent Screening Process – Fair Housing laws require uniform screening criteria, so making an exception for one applicant could lead to discrimination claims.

Addressing community concerns upfront isn’t just a requirement, it’s a smart move for standing out with well-received projects.

However, the property’s cost basis (what they originally paid) carries over to you, meaning if you later sell, you may owe significant capital gains tax on appreciation.Alternatively, selling the property at fair market value eliminates gift tax concerns, but your in-laws may owe capital gains tax on any profit.

Due-on-Sale Clause If transfer taxes are not a concern, the next consideration is the due-on-sale clause, which could lead to loan acceleration.

Quote from @Kaaren Hall: Was going for the best cost-of funds (lower rate)@Kaaren Hall So you were less concerned about your annual cash flow/return (IRR)? 

I misspell myself, :-) but the statutes to concern yourself with are12 United States Code USC Section 1715Z-19and theConsumer Protection ACTand a couple of others if you are interested.  

Your question is a very common question, and I can appreciate your concern here.

Is there anything i should be concerned about given there is no actual proof that he got sick from the mold other than the pictures?
