@Candi Kham,I recommend finding an accountant that specializes in real estate taxation and financial planning.

Taxation is at the individual level.  

If so, there are 20+ accountants on this site that specialize in real estate taxation. 

The full value of a Solo 401(k) may be invested into real estate, and this will be the better platform if you are considering leverage, as a Solo 401(k) is not subject to UDFI taxation on the debt-financed income associated with such transactions and an IRA is.  

I have enjoyed the "passive income" nature of rentals so I have to account for the extra taxation when doing new construction.Steve, you are exactly right in terms of ROI when the amount gets bigger.  

When a qualifying principal residence is sold, up to $250K capital gain per taxpayer that is due to appreciation can be excluded from taxation.  

However, it is still possible to defer federal capital gains taxation on property sold by using a 1031 tax deferred exchange.  

The even better part is that you can do an exchange, step up your basis, and delay taxation indefinitely if you learn to play the game right.

I would prioritize finding an accountant who specializes in real estate taxation over one that is local.There are 20+ accountants on this message board who specialize in real estate taxation.

Hopefully tax sheltered for the first few years, but then subject to taxation.
