Investment Info:Single-family residence buy & hold investment.

Luna,This sounds like you are buying a home as your primary residence.

Does anyone have experience buying properties from auction.com? 

Despite the weather and cold, I have always found it more attractive than the beaches in Florida or California.Unfortunately, I can't handle the politics and will probably never buy anything there.

Once you decide in a buy box and show them a financing letter from your bank.  

Why would you buy such a large lot if it's too expensive to maintain?

As you are pointing out - the expenses will all hit at some point if you own for long enough.If you buy a house that needs a new roof and a new furnace within a year... then you need to budget for those expenses in a year. 

If a fan is needed the tenant would buy a floor fan.

There is some complaints about the smell but that is fairly typical for memory foam when they are first opened up.Others have said you really have to wait at least 72 hours for it to fully expand before using or putting anything on it.EDIT - This is a special buy and has 2 days and 14 hours before it expires. 7% have been claimed so far.
