Are they required to publish financials or do they simple "intend" to publish financials? 

If your financial situation means you can buy a single property per year, or even a property every few years that is entirely okay.

@Elani SevillaTo finance real estate without a W2 job, focus on strong financials and business income stability.

There is no "magic number" of properties to own, everyone has different goals and financial situations to get to their personal "magic number".  

My advice: focus on building a strong financial foundation first save consistently, manage your credit, and educate yourself on real estate fundamentals.

I'm a financial planner who works with real estate investors - we have a client who plans to renovate a Clinton Hill (Brooklyn) property that has been in his family for generations into a multifamily rental.

What financial institution should I talk to?

You don't look through your mail hoping someone sent you a DMM piece on how to solve your problem.

I had to figure that out myself as well a couple of years ago haha as already mentioned, first things first, make sure you feel financially stable and secure. 

@Minji KimRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which is VERY important for stable rental income and low property maintenance/damage.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a Class A property in Class D area, what quality of tenant will you get?
