@Jordan Vires the best way to evaluate is to use 50% rule (See @Brandon Turner video "How to Use the 50% Rule to Analyze a MultiFamily Investment": https://www.youtube.com/watch?v=KQmChuIW_sY); do you think you could make the mortgage with 1/2 the rent? Not sure if utilities are inclusive or not, but you may need to take this into account as well when figuring out your numbers. So $550*16=$8800/2=$4400
If you were able negotiate the price to $700K and 25% down and have loans of $575K @6% you would be at $3150 (P/I) payment and the difference would be $1250 or $78 per door and if you were to get the purchase price lower without having to pay utilities it probably would be a good buy.
Additionally, evaluate the outstanding maintenance on the property such as roofing, flooring, interior/exterior paint, appliances etc and see what their life expectancy is. In all properties it good to have a Reserve Plan of these items, expected life and how they will be paid for during your ownership. Ask the current owner if he has something like this in place and if he does, ask to see it along with the rent roll for the past 5 years.
It appears the current owner is motivated to sell if he is dropping the price and willing to finance. It maybe worth exploring the idea of 100% owner finance as well; he could have a steady cash flow for the next 10 years but amortize the loan for 30yr and then re-fi the loan as you increase the value of the property.
You want a deal, but don't blow an opportunity explore other financing opportunities with the owner. Sitting down and having a coffee or lunch to understand his goals is money well spent. Do your due diligence!
Good luck, and please remember to VOTE on reply's you think have helped. This validates respondents posting and lets readers know that this information was valued.
Hope you have an excellent future!
