Hi Kin,Transferring your share of the property to your brother may have tax implications, including gift tax if the transfer is considered a gift.

If not, then you really need a strong legal structure stating how these properties will be governed going forward, including management, tenant selection, capital expenses, etc.

I'd also add to that that you are paying a 20% withholding tax on gross rental income. 

The first is that there's no consensus between tax professionals, and the second is that you will not like my personal interpretation.My interpretation is:Until the property is "placed in service" - everything goes into basis.Illustration.You buy a property July 1st.You finish rehab November 1st and put the property on the market.Your tenant moves in January 15th.The property was placed in service November 1st, and it does not matter that the tenant did not move in until the next year.Everything paid between July 1st and November 1st, including interest and utilities, goes into basis.

If 1031 is to be implemented it must be done on the property level.2. 1031 generally does not apply to IRAs since they are tax-exempt. 3.

Additionally, high-income earners with modified adjusted gross income (MAGI) over $250,000 (married filing jointly) may be subject to the 3.8% Net Investment Income Tax (NIIT).For 2025, bonus depreciation is at 40%, so consider leveraging it for eligible property assets like appliances or fixtures to accelerate deductions.

High taxes.

I mainly want to ask if these assumptions are reasonable and if there's anything I haven't considered:(1) multifamily units in NJ close to New York City, ~$1,000,000, 20% down payment, (2) Using the following assumptions: 4% appreciation rate, 6.5% interest rate and 5.0% refinance after 5 years, $10,000 yearly maintenance fee(3) ~$6,000 monthly rental and assume 3% increase yearly with 5% vacancy rate(4) Based on the above, the calculated IRR if selling at the 10th year is ~19% (considering tax benefits) and ~17% (without tax benefits).

When I did my first house hack in Columbus I showed very low income on taxes. 

During escrow converted it to a Roth and paid the taxes.
