I make around $110k+ per year, live off around $75K, have a mortgage ($1900/mo for rent, escrow, tax), around $40K in equity, and no other debt. 

This could make the sale more appealing by solving a logistical challenge for the landlord.Things to Keep in MindUnderwrite Conservatively: Make sure you account for all costs, including property taxes, maintenance, and potential repairs.

.-- Starts picking back up end of February when this tenant pool starts getting their income tax refunds and aren't broke anymore.6) Section 8: where is the property being advertised?

If your bottom line numbers on tax returns and W2 income are not strong however, this will be an abrupt dead end.

Property taxes are 650, insurance 160, outsourced property management takes 10% of the rent, and another 10% of the rent is set aside each month for future repairs. 3750 x 0.8 = 3000. $3000 profit, minus about $2300 in mortgage, property taxes and insurance leaves about $700 cashflow, when I move out.

@Pratik as @Neil Narayan mentioned, cash flow is very challenging due to the property values, property taxes, and soft rental market.

From a tax implication standpoint, it can be tricky but if done correctly, not a problem.

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).

-Management is low - you'll need at least 10% plus leasing costs - typically a month's rent for each lease-up, and sometimes a renewal fee as well-Insurance seems low-Are taxes accurate?
