Should I accept this tenant?

[Peter Morgan]

A prospective tenant showed up today and their  monthly household income is 1.9x rent and have additional incomes social security, job disability income etc ,income with this additionals comes close to 3x (little less may be 2.9) they have excellent credit score and no records of eviction was found but my initial impression was to turn down but they vouched that they never missed their rent payments and assured the same with me,and i ended up agreeing but did not yet draft lease. Should I go ahead and accept them?
