However, I see how one may struggle to change the email, since it may have important information stored or they've reached full capacity for making new emails. 

@Jeremy HartwigYou are missing a lot of important data, such as median income of the area, rent comps in the area, what current values are.You are buying on actuals, but in many markets that have low supply and have a lot of demand, it makes it difficult buy based on actuals.

One of the biggest lessons I've learned as an STR cohost, marketer & investor-friendly Realtor is the importance of thorough market research and setting up your listing based on data.

The market timing of rentals in my area is tremendously important.

@Larry Nielsen I like Jonathan's suggestion, but I think an important decision for you is what is your goal.

One of the most important things for you to know is that REI is very capital intensive.

This is why Cap Rate is so important, and ultimately cash on cash when you overlay financing. 

@Joey Samudio I would definitely recommend visiting the market you're wanting to operate in and more importantly meet the team you'll be working with.

Choosing the right contractors are important.

That may be able to get you important information.You should have no problem selling it as is and probably get all cash especially a two family in Queens.
