They seem to think it's too hard/time consuming for me but I'm younger and have way more energy and time to dedicate to this. 

@Fred,Your LLC could sponsor a Solo 401k.This would allow you to take income you generate from flipping personally with your LLC and make new contributions to the Solo 401k, thereby reducing taxes on your personal flipping LLC.The Solo 401k could accept a rollover from your current IRA and/or the other IRA you mentioned you have.  

@Tea MarieInteresting question because the pre-tax 401k contributions reduce your annual taxable income. 

I really like the positive energy u guys are bringing and the different ways to deal with things.

I understand that a larger initial down payment would reduce the monthly mortgage costs, but that just means I forgo more cash upfront which still factors into cash flow.

Asbestos siding to reduce fires and damage and lead paint to be longer lasting:-(

If you find a place that reduces that significantly even with you coming out of pocket a few hundred a month, then it's worth it because you will still be saving money each year.  

.- other than reducing seller's taxable income, what are other reasons why this option might be attractive.- what kind of rates have you negotiated.Share your story!

Less so in DC proper, more so in the suburbs.Energy costs in this regional are pretty moderate, so for most people the aesthetics of a house are more important than the small energy savings.On a typical median priced home in Montgomery or Fairfax County you would see about a $20k drop in value by adding panels.

It could also be part of some of the new energy codes but I don't have those yet.
