(aside from the 1 or 2 homes that have stunning overlook views).When building out your buy box, are you all using the averages, or are you basing your min/max on the cream of the crop listing revenues, even when there aren't clear reasons as to why they are performing so much better than others?

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).

The home was built in 2006, great neighborhood, close to the highways, close to everything new that is being built, close to a military base.

If not, then what he is trying to do is to avoid his reputation going down the drain and lose any future credibility and trust in the future. personally I am just familiar with the basics of buyer seller representations in a general sense you will need a FLA Broker or Attorney to describe to you based on the documents you have if there is a Duty from the agent on this transaction..
