A seller could misrepresent a property, repair issues could arise, all of the same reasons an investor could change their mind on a purchase that are discussed here at length can apply to a wholesale deal. 

I try to keep in mind it's a marathon, not a sprint.

I finally got an older guy call back who saw it 2 weeks ago and he says I can't get that apartment out of my mind and is it still available, signed the lease yesterday with the occupancy date I wanted so its all good.    

Can someone please give me a good list of question to keep in mind when im trying to find a good real estate investment property to buy?

Whether you owe 50% or 100% on a property makes no difference if you can not afford the payments.Also keep in mind when you have excessive equity in a property and the markets turn it is your own cash that is at risk not the banks money.

It crosses my mind some days to just sell it but another home would be just as much so not much gain. 

In addition, the more creative real estate finance minds aren't handling these smaller loans.

There are some discrepancies in regards to the time value of money and I'm hoping you will go over the book to get a really good feel for it.Once you understand all of these concepts, you will really understand investing.There is a lot that goes into the projections, however.Keep in mind that once you start thinking of the future sale price and the future cash flows, you start to think, HEY.........

Hey everyone, I always get excited talking about real estate & I'm excited to have found this community of like minded individuals.

The thought had crossed my mind but nothing serious.
