Account Closed Thanks that sounds like a great list! 

I am looking for any advice on job cost accounting software.

A couple of years ago I created a Solo 401K account using funds from a frozen pension which was rolled over into the Solo account with a check written out the name of the solos 401k.  

I simply have a lease agreement and in the lease agreement specify where the rent payment needs to go such as bank account info and account number.

And you should treat it as such (separate bank accounts, contracts, insurance, etc.). 

Account Closed Thanks!

Net funds are distributed to account of choice. 

Account Closed  that makes  sense  however at 250 to 350 that's not a very big mortgage unless its an old one and is sup prime.

When I tell him all of the ways you can account for these things and budget it into your expenses to make sure you still come out on top, his counter is "then why isn't everyone doing it?"

The Bigger Pockets buy & hold analysis calculator does not take into account the tax benefit of long term ownership, which is substantial.
