Can easily get a 20% referral fee just for sourcing and handing off that lead.

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).

I started with Podio (Premium) and already I am seeing it's limits without having to spend a lot of time customizing it or hiring someone to do it or even paying a monthly fee to some third party.

Annual fee $25.PenFed - max 3 other properties, 89% LTV Regions- yes HELOC but no LOC SCCU Florida 70% LTV, 6.25% interest only, not LLC Sound CU "non-owner occupied HELOC, capped at $150K and interest rates are prime + 2%, 3% or 4%, based on credit, not to exceed 70% ltv.”TD Bank TIAA Direct was EverBank Tower FCU, all states except TX, max 45 DTI, green card ok.

There is a not so inexpensive fee - anywhere from 5k to 100k depending on the program and they take a % of each deal. 

Make sure to account for property taxes, insurance, and any HOA fees, as those can vary significantly in different markets and impact your cash flow.

I was one of the fortunate ones that was able to get out of the contract and after all expenses (forfeited deposit, legal fees, holding costs, etc) lost less than $20k.  

There should always be timeline contingencies factored into each projects specifics.

Avoiding accessive PM fees (personally I recommend most people self-manage)These will eat away at your ROI.

But that is calculated after expenses and depreciation is factored in.
