I agree - seems like a gamble definitely not worth taking my friend

This is fairly accurate if you hold property long term.

Although I did throw in what my rent was and it was pretty accurate.)

Doesn't sound accurate.

There is no way to have an accurate way to give them an offer.

I have a property mgr for 10% and have to date not had a vacancy.However, being in commercial real estate, I know there is always that gamble.

The only accurate way to do this is by analyzing other similar sales.

If your rent estimates are accurate, the rent yields seem rather poor on these, barely more than 1% a month including closings costs and repairs.

The seller or real estate agent may know something you are overlooking.One this is for sure, if you do not know more about the properties, neighborhood, and target market than anyone (including the seller); and be accurate in predicting the realistic future that is not based upon any blue sky assumptions, this could become much more of a challenge than a reward.Best of luck.

Not sure how accurate it is.
