VA buyer...dead deal, put house back on the market.Under contract again at 149K within 2 days with a USDA buyer. 

I did not fix (thanks to the engineering report) and buyer purchased as is for the original selling price of 199k.

Agents don't like to work with wholesalers because the nature of wholesaling is to get a property under contract for a price that leaves room for an end buyer to pay a wholesale fee, and also has some room for the end buyer to make some money in the deal.  

I only pointed out that it was my first time buying a home because I'm pretty sure, as a first time buyer, I am elligible for certain programs that allow me only needing 3% down.

I liked it because it was intentionally simple and it was written with investor buyers in mind.

Lenders are so efficient it is on the auction block where buyers have to pay 5% hammer fee to the firm and bank to acquire a property at market price. 

There's probably more than I'm not thinking of right now and I'm probably being unrealistic, but this is what I'm hoping for with my next real estate purchase, now that I'm a wiser buyer.  :-)

I go to the open house and walk the house and write up a scope of work of what the investor most likely did. when the listing agent starts asking about me thinking I'm an interested buyer I explain to them exactly what I'm doing and if they don't want to waste their time with me I understand.

Right now where I'm at it's definitely a buyer's market so I think I bought it at a good price ($168,000 and current rents are $2100/mo at that property). 

The issue is that you are dealing with two distinctly different products each having a different driving factor.SFHs are not specific built rental income properties, therefor the price is driven not by rent but rather by the whim of home buyers.
