Of those, the two I am considering: A 5 year fixed/arm, resets every 5 years, 25 year amort.

I am a fix/flipper in a tight market and looking to expand my opportunities past the usual. 

I had a quick call with my CPA about what I can or cannot deduct if I purchased a duplex for $600K using 100% under a 30 year fixed VA loan.

Thank you this is a 1 bed apartment in a high-rise, so we don't need major fixes that are shared in the building such as HVAC, roof, moving electric/plumbing, etc.. just the items listed above.I have no relationship with vendors though I see many advertised online with reviews which I'd base my choices on. 

Or will you dig a fix hole and go to war with a landlord?

I could tease this out more, but the main reasons are 1) a down economy, 2) an emerging economy, 3) AAA property locations, 4) lack of credit available, and 5) historical buildings (very sturdy construction, 3-4.5m ceilings, etc) that are very undervalued at the moment for mostly aesthetic reasons that can be fixed quite easily.

Better to have fixed rate long term debt.Which direction you choose to go on your refinance really depends on your risk tolerance.   

Then, either fix-and-flip / rehab it, lease-option it, etc.You might use it in a probate case ... 

It was about 50/50 on wholesaling and fixing and flipping.

Make sure the title is good (sometimes foreclosures are done to fix title issues that cannot be fixed otherwise, or in lieu of a quiet title suit).Close the property, best before the two weeks is up.Wholesale it out.Sometimes, if the property is under contract, the foreclosing entity will postpone the auction.Good Luck,Jim
