Sales agent gets slightly more aggressive than I like, but other than that, they seem more trustworthy than other opportunities like this that I come across.    

if I have no money into the deal and bringing in $200 free and clear every money hell even $100 with no other expenses these usually come through creative deals or owning notes but I would do it. 

@Albert Gallucci as many have pointed out, in the commercial space of 100+ apartment buildings and offices, property classes have some pretty decent industry standards.We started applying these to 1-4 unit properties around 10 years ago, which you can verify on our blogs, because we saw too many newbie investors not properly taking into account things like, neighborhood status, tenant pool, property condition, etc.Unfortunately, there's no industry standard for this, but you can use some basic logic to think your way through your own Classifications.

I would check the find real estate agents link up at the top.

But, if I were in that situation I would probably not be buying any directly owned properties at all (and would instead be investing in a diversified fund).

as others have stated, if a RE agent does not believe they can sell the property, find a different agent that believes they can sell the property.  

out west here we do our own deeds we never use an agent or title or an attorney..

Use a buyer's agent that knows the market, contracts, negotiations, etc.If you really want to learn about investing, get a job in property management. 

For (D), if I don't have a management agent, do I leave it blank?

@Timothy Frazier Yes, the only reason to use HML as a down payment is if the property is "mostly turnkey" AND you don't have the funds to renovate AND you have strong CMA comps from a real estate agent that supports that the fact that you are buying a property that is under valued AND your renovations would push that so that you could refinance.
