It is a fairly signinificant set up fee and monthly charge. 

Of course our big motivation is commission but you can get commission or a referral fee or something in an off market transaction if done properly.

I mainly want to ask if these assumptions are reasonable and if there's anything I haven't considered:(1) multifamily units in NJ close to New York City, ~$1,000,000, 20% down payment, (2) Using the following assumptions: 4% appreciation rate, 6.5% interest rate and 5.0% refinance after 5 years, $10,000 yearly maintenance fee(3) ~$6,000 monthly rental and assume 3% increase yearly with 5% vacancy rate(4) Based on the above, the calculated IRR if selling at the 10th year is ~19% (considering tax benefits) and ~17% (without tax benefits).

Quote from @Patrick M Nichols: Cogo is a total scam... lots of fees on the front end.

If customer service has been a major concern in your search, uDirect is known for being responsive and transparent about fees and processes.

They will take the permit fee and send an inspector that will provide some assurance that the work was performed correctly.

Anyone over 18 fills out has to furnish their social security and driver's license numbers, and pays a fee for a credit / background check.

When you add on your new lease fees, lock box fees, inspection fees etc. the percentage creeps far higher.

What costs/fees should I look out for?

I am looking into a company right now that does rent guarantee insurance and also does in lieu of deposit will issue a bond that the tenant basically gets charged a monthly fee for.
