What candidate would you prefer?

[Maria G.]

I have 4 solid candidates, which is making it hard for me to select:

A: Doctor (ending residency in a year at a major hospital) and engineer (working for a big high-tech company), moving from 40 miles away to be closer to work. 750-800 credit, 4.1 income-to-rent ratio, 40lb Husky dog (not an ESA, but professionally trained). I talked to the current landlord (where they've resided for 4.5 years) and he said he didn't notice any damage at all (in the two inspections since they got the dog) and they are great communicating. 

B. Junior engineer (working for a big high-tech company) and mom (REI agent, self employed), moving from out of state because of the "back to the office" policy from the high-tech company. 750 credit, 4.3 income-to-rent ratio, 13lb Cavapoo dog. My property is 15 minutes walking to the engineer's work. They can't offer landlord references for the dog because they got the dog after they purchased the current property, but they promise he's very well behaved.

C. Police officer and part-time spouse with a 9-month-old baby. 780-800 credit, 5.2 income-to-rent ratio. 

D. Engineer and trainer (both working for the same big high-tech company as B, in another nearby location one of them and at home the other one), moving from out of state. 800 credit, 2.4 income-to-rent ratio, 2 adult cats. They provided a letter from a prior landlord who stated that even though they got the apartment furnished, the landlord didn't find a scratch even in the furniture.

(I will check landlord references for B, C, and D tomorrow.)

I have my thoughts of what I think would make me lean to each, but I don't see a major pull to any. Personally they were all very nice too. Do you have any thoughts?

Thank you!
