@Victor SolomonYou may want to focus and prioritize other concerns than just the loan (though understandably without the loan, the whole deal may fall through). 

But my understanding is that the majority of such properties in each major city are handled by a handful of brokers, and many never make it to the open market. 

With the Duplex now, my understanding is I file as though the rental half is a separate property and cut all expenses in half as a write off to my rental income (property tax, insurance, maintenance, improvements, etc...nothing was done specifically to either unit it was full home external work like garage and railing repairs, painting) as well as depreciating the half of the duplex that is a rental after calculating basis.It all seems very straightforward to me but I know I'd be naive not to have a second set of eyes with a professional given my lack of experience.

Mistakes that I have seen made generally always come from a lack of due diligence and understanding.

Having listings really helps you understand what the buyers are willing to do, and each of my listings would have 20-30 offers on them, with about half of the buyers offering 50k+ in DD and the other half not. 

If you’re looking at San Pedro or Ambergris Caye I would make sure you understand water, sewer and golf carts infrastructure and permitting.  

I am not convinced that granite countertops will allow you to increase rent enough or reduce vacancy enough to cover their cost.In a typical smaller house you might spend $6000-8000 on granite countertops, if it even allowed me to increase rent by $100/month it would take 5 years to recover the cost.Our tenants seem to be happy with laminate countertops that cost me less than $1000 to self-install ( I have done this in multiple houses).Can you help me understand the math of ROI on this?

From my understanding, triple net leases can present an appealing route for those venturing into commercial real estate investing.

In addition, Brooklyn is filled with young professionals and has a lot of fun stuff to do.2) I want an appreciation playI understand cash-flow near NYC is tough, so I want the appreciation play to be strong via the forced appreciation and via normal appreciation.

I deeply appreciate any insights, advice, or anecdotes that you can share to help me better understand Subto financing and navigate the compensation aspect for real estate professionals.
