Renting to Tenants with no prior rental history

[Nicolas Chambers]

Curious as to what your policy is for renting to tenants with no prior rental history (3 years out of high school, they're not trying to hide anything). 

Background:

Newly engaged 

One is an Electrical apprentice (1 year w/ current company, 2 years with prior company)

The other a Barista (3 years with same company)

Good credit.

Dual income is equal to 3.5x the monthly rent (assuming barista is including her tips in this figure)

They have savings. 

Have heard/ read, double just the double the deposit. 

Thanks in advance for any input.
