I will likely be financing this, which is why I need to make sure it covers the carrying costs plus some. 

@Nicholas StevensonGood suggestions to ask the seller if they can carry the note and talk to other lenders.Also a reminder there will be tax implications when you cash out on the crypto and that you should consult with your CPA before you sell.

@David ChwaszczewskiAs mentioned, the Solo 401k (sometimes referred to as a type of QRP) will carry many benefits over any IRA.

I was contacted by them today, and curious about how strong the program is once your "certified"  The certification doesn't seem to carry any actual legal license. 

There's programs that allow seller carry backs (for example up to 90% CLTV).

I have not taken any depreciation on this property.It was held in this corp since 1967 and the tax returns show a "land" value of $15,000, carried over for many years. 

SO you have to decide what you want.Having said that, most General Contractors carry a few jobs at the same time.

Capital gains would be 0 because he has not hit the threshold for gains on a primary home sale.Dad’s remaindership share (portion that was my brothers) is 35% and carries a $0 cost basis.  

Someone decides (that carries significant consequences) whether an application is approved or not... 

The program looks at location, property value, amount owing, interest rate, taxes, insurance, rents, condition, etc and several exit strategies.When we make an offer to buy, we can offer cash, subject to, wrap, seller financing, lease option, seller carryback and so on.Obviously if we wholesale the property, there is no carrying management needed, and if use a lease option to sell, the optionee is responsible for maintenance and repairs.
