The management company replaced some of them, however there are still several other fees related to the theft that we are trying to get reimbursed for (they told us we would not be charged, they charged us anyways).

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

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.

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).

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

Basically you find these distressed properties in pre foreclosure, probates, divorces, or just ugly vacant properties. then you calculate the Max allowable offer and if it makes sense you call up the property owner, get it under contract for dirt cheap, then you assign the contract to a cash investor for an assignment fee. this is the general idea obviously it gets more in depth, but its finding deals that you would buy as a fix and flip or brrrr, and instead of actually buying it you sell it to other investors.Ahh I see, thanks for clearing that up.  

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.

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

The northland MAREI meeting and the main monthly meeting at MAREI have a minimal fee, or for $99 a year you can attend all of them for no extra charge - northland is in person, the main meeting is still online, both are great ways to connect and learn. 

So long as your original fee to open the account is booked as a personal contribution to your business and all the transactions are business-related, it seems like your best solution until you get back stateside.
