Sometimes it takes a bit of negoiating with the seller to get them to see their expectations on price are unrealistic.

I am not asking for a unrealistic amount since I already did a lot of analysis myself on what is currently available and how much similar units were rented out in the past three months in my area.

If you have a scattershot approach like @Jake Thomasthen for sure, just make a bunch of drive-by lowballs and wait until you get lucky.If you have a more targeted approach like @David Neelythen making unrealistic offers is just going to piss off agents and sellers.

Not really unrealistic to expect that. 

But if you're just starting out and getting your feet wet, I don't think it's necessarily a bad deal, so long as your expectations and goals for it aren't unrealistic.

Why would an agent want to waste their time, to do all the leg work for someone who is just going to offer unrealistic prices in what is still a sellers market in most price ranges with a list to sale price ratio of over 95%.

To find 3 distressed properties and think that you are going to get 3 deals is unrealistic.

I'm not sure where you're getting the $15k limit, but it is a bit unrealistic for what you want to do.

Sadly, this is unrealistic.

Don't start by having and unrealistic budget and force yourself into working with bad contractors.
