I’ve had contractors get scary with me and act physically threatening because I failed to recognize this early enough.

The purpose being to purchase a rental property without any money down.I recognize there are a few possible challenges and threats with this approach:Finding such a property is more difficult than simply purchasing something for sale off the MLS at market price.Finding a hard-money/private lender willing to lend 100% of the purchase price.The possibility that the refinance doesn't go through for some reason and I'm stuck with an expensive hard-money/private loan that I can't pay off when due in 6-12 months.Recognizing those:Are there any potential challenges or threats that I missed that are unique to this scenario?

Is there any scenario and/or implications that we may not be recognizing and could be to our detriment? 

But I recognize it..

How are agents who are successful recognized?

If you consistently analyze properties, it will be much easier to recognize a good deal when it shows up.

Human nature is that we will avoid taxes, unless forced to recognize income.
