If there are comparable use those rents and sale prices to determine the cap and apply it to the present rents in your property.

@Chad BaileyThe following IRS document sheds more information on the ROBS 401k program. https://www.irs.gov/pub/irs-tege/robs_guidelines.pdfAlso, here is how the ROBS 401k program works in a nutshell.A new C-corporation is established.Corporation sponsors a new 401k/PSP.The IRA funds are transferred to a new brokerage account opened for the 401k/PSP.The new real-estate corporation issues stock shares to the 401k/PSP for the benefit of the participant.The 401k participant must be an employee of the corporation and he or she may take a reasonable salary.The corporation owner's family members may be employees of the franchise business and receive reasonable compensation for their services.To the extent that the corporation generates profits and elects to distribute those profits to the owners of the business, the percentage of the profits associated with the shares held in the 401k/PSP will flow back to the 401k/PSP brokerage account.

Size is going to be the biggest determining factor here.

It doesn’t really matter.....assuming the mtg foreclosing was Recorded before the tax lien was, the IRS has 120 days from the sale, or from receiving proper notice of the foreclose didn’t serve them, to redeem (pay you back your purchase price.  

How should we determine ARV on a property that's in a nice area of Macon, GA with no similar comps nearby?

In the situation where the parents are exchanging into a TIC in the replacement property, this seems to be a different situation since it's actually the parents LLC which is taking title to real property via the TIC, so if an heir was to invest in the property as an LP I feel the IRS may view this differently but am not sure.

In short, as a Realtor I have access to the MLS which allows me to save time, more accurately determine comps, acquire tax and mortgage information not readily available approximate value to be approximately by these companies and that the information is not always updated in a timely manner.

I have been scouring the internet and testing out some marketing strategies looking for my first deal with no luck so far, but I am committed and determined. 

Being confident in the numbers and recognizing YOUR strategy allows you to be disciplined in determining how far you’re willing to go in the purchase or sale of a property, realizing of course, that sometimes the best deal is the deal that’s never done.
