Roth IRA vs 403b conversion to SDIRA

[Matt Henshaw]

I have $100,000 in two separate retirement accounts, a 403b & tradition Roth IRA account. I have been retired for two years and am currently 56 years old. Here are my questions:

1.  Would it be a bookkeeping nightmare to try roll both of these retirement accounts into one SDIRA to purchase a property of about $170,000?

2.  If I was to purchase something less than $100,000 and only use one of these accounts, which retirement account would be best to move into the SDIRA to use?  (from tax purpose standpoint?)

Thanks!
