Taking Duplex rental history into consideration for analysis

[Pascual Torres]

Hello

Complete noob wanna be investor hear.

We found a duplex that we are interested in. When doing our analysis we used the advertised rental rates which yielded 9% cap rate. After reviewing documentation from the seller, it looks like the advertised rent rates are very new so there isn't history on payments at these new rates.

How does that change the analysis? Do I keep using these new rent rates for analysis or are they irrelevant ?

Is raisesing rents and putting up for sale and advertising a certain "cap rate" a known sleezy sales move?.... lol

Regardless of the history , I feel like these could rent for more than the advertised rent rates. I confirmed my feeling by asking other tenants around the block what they pay. There is 8 identical buildings on the same block so I feel like it is good comparison.

Thanks
