As income rises minimally it will be almost impossible to pay off the debt when house, car, marriage, kids, etc. come into play.

Years ago before marriage, I had a good buddy live with me in my house as roomies.  

Best of luck to you and congrats on your soon to be marriage. 

You asked how the rest of their application looks well this is what I have so far:Husband-31, Wife- 28 and Son-2Employment- both employed together making almost 4X,s rent of $1250Background- both have NO criminal background Evicitions- Husband has 1 from 7 years ago prior to marriage and Wife has No evictionsCredit Scores- Husband 676, Wife 690Personal References- They used parents as personal references mom and dad.

This will test the waters.The reason for that statement - to which I agree - is that this is more than a long term thing - it's like a marriage.  

Here in Florida, records like mortgages, deeds, marriages, "and" arrests or things like tickets are recorded.

sometimes the records are not correctly indexed, sometimes people's names are misspelled, (happened on a property that I bought where my name was misspelled), or people's names change through marriage, divorce, remarriage, junior, senior, other extensions  etc. 

If this marriage doesn't last, who is going to stay in your rental and make the payment?

Living in Texas though, common-law marriage is a very real possibility.

Their marriages, functions and their future family visits at least few times a year, we need good home equal to our current home level.
