@Jan Ferry-Axman,Your understanding of the rules is correct, as 'disqualified person' you are not allowed to provide any services to a qualified plan.

youll want to speak to them about your DTI and get that figured out before making any moves, youll also want to discuss the post scenario for what your going to use the money for, ie (this refi qualifies but future refi will not etc.)

That is for my already contacted and at least pre-pre-qualified.  

Can an owner of one rental property under an LLC easily qualify as a Real Estate Professional while also working a full-time job?

All with 15% down based on purchase price + rehab dollars using ARV from the start AND projecting future rent to allow you to get 75% of the future rent as extra income to qualify for the loan; 30 term, rates around 6% these days, no pre-payment penalty so you can sell when ready and repeat.

Yes, IRA and 401k are qualified retirement plans and you must follow applicable rules.

Would that qualify as a tax deferral?

now take a 1200 dollar renter in a nicer property.they need 3600 to qualify take off  1600 for rent utls etc. now they have 2k a month to live on..

When talking with my mortgage broker, he told me that as a 1099 contractor, I will need to show 2 years of work history in order to qualify for a pre-approval.

Dogs whose sole function is to provide comfort or emotional support do not qualify as service animals under the ADA."
