We're talking 7 figures loans so I'd like to hand over something that looks professional, contains all the information someone like you would expect to see and even what format.If you could share what was included in the best one you saw or what's the most common thing investors forget to include that would be very helpful. 

Be careful not to make the common mistake of thinking that just because you find a good deal that investors will invest in it, lenders will make you a loan, and the seller will choose your offer.

However, it's a market that we're comfortable with, great schools, and high-quality long-term renters are common.

My cost seem to be half of what I see other landlords paying for roofs, HVAC's etc.So far on all my properties I have been under the 80% mark to finance the repairs and the mortgage with out any personal capital (Other then very short term when I pull that money out when we mortgage the property).Are there errors to my ways? 

I guess since we've only been buying duplexes, I made that error BUT it's still good.

In other words if you live in a duplex, you can only deduct half of your expenses such as depreciation, landscaping, common utilities, etc if they benefit the entire property.

Property taxes are shockingly low in most areas of NYC (despite common belief), vacancy rates are also extremely low (I've averaged 100% occupancy across multiple properties in 5 years without even trying hard). 

Subordination agreements would be recorded (and they aren't all that common), so just be sure to watch out for them.If there are three loans recorded, and no subordination agreements, and you buy at a foreclosure sale of the middle one, you are buying it subject to the first one but the third one is wiped out.

Don't forget about seller financing, it's more common in multi-family.

The commonality in the three options is the action to "get started" and take the career leap.
