That's because if for whatever reason things go south, depending on your jurisdiction, a foreclosure can eat up a lot of capital and time, there's also the threat of federal/state tax liens complicating matters. 

aaron buying notes is quite complicated if you are not in on the origination of them. 

I'll share that we avoid lending on wholesale deals because they can be mind-numbingly complicated compared to the amount of work involved in a simple purchase and sale (REO, probate, private party, etc.), for the identical return.If it is the numbers, I still don't see the problem as your lender not knowing how to evaluate a deal, especially if they gave you their criteria, as you indicated.

@Alicia Ogunmiloro,As @Wayne Brooks points out, notes are a complicated asset.  

It does make the return more complicated though and for straight simplicities sake i know people who haven't claimed it because in the end it usually is close to netting to 0. 2.

If you rent more than 3 years, you'd no longer qualify for the homeowner credit when you sell, so you'd owe capital gains taxes, depreciation recapture depending on how long you hold it unless you do a 1031 -- just gets more complicated.  

It's a way to get cash flowing in while work is still being complete on other, more complicated units. 

Farms by their very nature are a niche market, a whole life style and the improvements (house and out buildings) are only a portion of the evaluation.Sticking with crops only, there's a value/acre on the crops.Glad you understand all these complications, as us city folk can only appreciate the pretty pictures.

House flipping takes a lot more work than people typically envision, but is also less complicated than you might be anticipating.

Plus, the commercial properties are more complicated than residential properties, typically.
