Same for heating, although the range is more than the 20 I mentioned, can be 40 -60 degree rise or more with newer units, between the intake and the outflow, AT the furnace; however you likely will lose some of that gain for a variety of reasons including length of duct run; are the ducts insulated or not; is the space properly insulated, no insulation, or somewhere in between?

If the smell is musty or at all resembles 'organic growth" (mold) then check the air handler, intake, duct lines, and filters.  

Quote from @Daniel Benyamin: Hello Everyone,I'm looking to buy an investment property in New Jersey, I was looking for condominiums because they are selling for around $150,000.00 for one bedroom, and to purchase a multifamily with 4 apartments in this area will cost somewhere around $800,000.00, so basically, through the years I did not get to any investment that required a significant investment because I did not want to carry a large debt and I don't have a large sum to put as down payment.So my hesitations about purchasing a multiunits are as follow:I don't want to carry a large debt.I like to buy the next property in New Jersey because I'm familiar with the location.I'm aware that the purchase price is high, and I'm unable or I'm reluctant to invest, so I may be in need to consider a new location to invest in.I hope that some of you  who experienced the same "problems" can share your experience and how you wore able to invest successfully.Thanks,DanielDaniel Hello Daniel,Most of my other clients have experienced the same thing as you, what they did was they looked out of state to get better deal for themselves, now it may seem daunting to invest out of state especially since you aren't aware of the location, that's why it's always importatn to surround yourself with a great team if you are wanting to consider a different location (eg a realtor, good PM, lender, contractor, etc) If you are interested in taking this approach, I recommend you read this article on OOS investing.

Some get caught up in taking advice from non investors. 

I’m debating in taking the equity out to purchase additional investment property’s? 

@Johanna V. biggest congrats in taking that leap of faith!  

I'll go to properties that my clients have interest in, take videos and extra pictures, have a FaceTime session, whatever it takes to help my client get a good feel for the home and if it will work for them..  

Ask tenants if there's any leak, if anything got worse since they moved in, ask how the heating/cooling is, ask what kind of issues they had since the move-in. Take
