For Owner Carry-Back, what are the guidelines or rules/ regulations that should be followed? 

I was wondering what the best way to structure a deal with seller carry is?

I used that book for all my seller finance contracts and bout wore it out.. most of my seller carry in those days was 10% to 18% for 5 to 10 years..  

The home office deduction cannot increase your passive losses:You can only deduct home office expenses up to your net rental incomeIf your rentals are already showing a loss, the home office deduction won't helpExcess deductions carry forward to future yearsMust apply §280A limitations first, then passive loss rulesExample: 🔢Rental Income: $24,000Regular Rental Expenses: -$20,000Net Before Home Office: $4,000Home Office Expenses: $3,000 [using allocations, not the Simplified Method]Result: Can deduct full home officeCounter Example: 🔢Rental Income: $24,000Regular Rental Expenses: -$26,000Net Before Home Office: -$2,000 (Loss)Home Office Expenses: $3,000Result: No home office deduction this year (carries forward)Reality Check: 🤔Let's be honest - while technically you need to:Calculate net rental incomeApply §280A limitations [Consult your CPA on this!]

The approach involves using a hard money lender (HML) to fund 75% of the purchase price while having the seller carry back 25% in a second-position loan, allowing you to flip the property with little money down.

It may boil down to your preference on product they carry too. 

Given that the property was worth $390K in its current condition, I saw an opportunity to make the numbers work while keeping my upfront costs low.Instead of increasing my cash offer, I negotiated a $25K down payment with the seller carrying the balance for two years through owner financing.

As luck would have it, last night Person A messaged me (late) notifying me that the deposit could be carried over for use by Person B.Thanks again!

For example, if I send my son money for books, can I do so as a property manager fee so that this is also tax deductible.4) If my son, finds the monthly payment to be to much while he is in school and I end up shouldering some of the costs, how long per IRS rules can I carry a loss on the property.Any help would be greatly appreciated.Thank you.
