For example, if a parent co-signs for a child but the child  graduates, gets a job and starts paying the loan that debt can be excluded from the parents DTI as long as there is proof and the payments from the child have been on time. 

@John Williams politicians at all levels of government are taking away landlord property rights to protect slum-tenants.We'll soon be like Ontario, Canada where they can't charge application fees or security deposits and it takes 12 months to evict a tenant.Unfortunately, landlords are too cheap to make political donations to stop the madness:(

My parents completed a 1031 exchange over 2 years in their own names – they file a joint tax return.

Honestly if your DTI are at the limit already and your parents need the money, sell it.

She would want to have a single parent with 2 kids live with her who has 0 credit (not sure how this is possible) and an eviction due to a bad divorce situation.

Every parent of small kids will want a tub.  

My and my soon to be wife both graduated college at the same time and we make a combined $150k/year ($75k each) We are still living at home with our parents to save money, and we want to build wealth in real estate. 

And if they are 50-70% leveraged, AND the equity is performing at 5-7%, then most people would be living off of most of that come and have only about 10% of it to donate or sacrifice.

I’d had two large mortgages from my parents but none through a bank.

Not surprisingly, I mostly went to other kid's houses that had some space that was not constantly next to parents.
