This is also why sophisticated investors only look at IRR because one has to look at an investment over the entire holding period by accounting for the magnitude and timing of cash flow.

Echoing what @Andrew Beauchemin said, you can find out owners of buildings by looking at property tax records on your county's appraisal site. if the owner is a LLC (which is usually the case for larger multifamily), go to your state's secretary of state website and look up the business in the business records search. i'm not familiar with pennsylvania, but that's how every state I've looked at before operates. there is usually an agent of record who oftentimes is the owner, however, for a larger, more sophisticated owner, it could easily be a lawyer or someone else.if that fails, a broker is your best bet. they'll have the relationships with owners and other brokers you need. as others have said, it's hard to go off-market without a track record, but maybe by showing your current portfolio and explaining your desires, you may win someone over :)

It's not that simple math is wrong, it's just that you can open your mind up to much more possibilities, like investing in appreciating markets, once you become knowledgeable about 2 things, 1) Sophisticated Math and 2) Economics so you can read the future of the market.Personally, I don't know how any Investor doesn't want to learn enough about Economics to get a gauge on how the next 10 years in their specific Area of investing may turn out.Will it be like Detroit, which went bankrupt but you could easily have seen that if you paid attention to the 3 Big Auto Makers?

. :)Usually, the bigger the deal, the more sophisticated the operator is, and thus better records.So if you're doing more smaller deals, you may have to settle for less, but you can try and get creative during due diligence to verify your underwriting assumptions, like knocking on those same doors and getting a signed estoppel. :)James

Nevada, Have you tried the casino's?

That is why most sophisticated sellers want some down payment so they have money to make their tax payment. 

The only similarity I see is BitCoin was an investment vehicle which until recently was the domain of the professionals who understood it well but now its become a mass market casino where everyone with $200 in his pocket thinks he can partake and make it big.

I'm starting to model some much more sophisticated scenarios of buying investment properties, but before I even got too far into it, I began modeling the impact of inflation on your paycheck and personal expenses.For example, I ran four different scenarios.No inflation on your paycheck and personal expenses: the $5,000 per month you earn is still $5,000 per month 40 years into the future.

@Scott EdwardsI think part of the reason this isn't usually taken into direct account is everybody's tax situation, bracket, etc. is different, so it's very difficult to estimate how owning a particular property will impact their tax liability for the year.With that being said, it's a definite benefit of owning real estate and more sophisticated rental property calculators do show the tax benefits (like depreciation and mortgage interest deductions).
