@Scott McLaughlinPaperstac is a great site to connect buyers and sellers but remember the expectation boils down to you and the seller and understanding the process.It’s like the eBay of note investing.

Don't pay for information that is readily available for free on this forum.

If that is the case, then you will be paying on the capital gains taxes of the sale.  

If you know the market and where to price your property, a listing agent is really not going to add a lot to the process and will cost you 3%,  Now before I get blasted by agents posting how mush they add to the sale on the listing side, I will say that if you are not familiar with the sales process, maybe you need to pay the 3%. 

Are they paying market rate?

He told me that he always gets the seller to pay though. 

We are paying for commission for agents instead for sellers paying that.

2) If not, is there another way to run the comps on a similar site?

if it is just the financial side holding you back - let your bank be your partner… or see if you can borrow the money from a family member who knows and trusts you -  without actually partnering with them on the control of the deal itself (pay them interest - or even bring in on the lien to secure their position the first time) - but let them be the finances and you control the project. 

However, I have seen some weird listings on this site and it also does not have the best reviews.
