I've only seen a handful of property management agreements - curious on the general consensus as to whether a specific clause such as the one below is pretty much standard or not?

I think you're so right that it depends a lot on factors specific to each investor's comfort level. 

The only thing that scares me about this property is that margins are thin about 3k per year so anything that I missed may make this deal less desirable.

The margins for error seem slim on that, and you are essentially buying it for more than that.If opportunity is going to come to you at an inconvenient time for you, then it better be worth it. 

This loan type would be very specific on requiring you to have 2 years of tax returns if you are self employed. 

Advantages for me: slightly less paperwork, fast approvals, leeway if your credit score is borderline for a specific rate, relationships, flexibility to lend on properties that need significant repairs.Main con is slightly higher than average interest rates and shorter terms, for me at least.  5-6% and 20 year amortization is generally what I'm paying.Hope that helps,- Tom

If you are specific about what you mean by an "investor," an Agent will be more helpful. 

I owe specific thanks to @Scott Trench for his book, Set For Life, which played a big part in my decision making process, as well as @Brandon Turner and @Joshua Dorkin.I've spent the last 3 years behind a desk as an MLO for one the country's biggest hard money lender, working specifically with brokers across the country to facilitate loans on behalf of their clients, and the learnings from that position and the time I've spent on BP, reading the BP publications and forums has given me the confidence to undertake this life changing pursuit.If you or someone you know/partner with is looking for financing on any upcoming real estate investment, let me know - I strive to be of value and have an extensive lender network to ensure quick terms and reliable financing.

I realize that some money is better than no money, but that leaves tighter margins if something else comes up, market changes, etc.

@Dave Foster or @Bill Exeter can give more specific details.
