Show HN: RealtyHop - NYC Investment Real Estate Sorted by Yield

Hello HN! First off, there are already some things I know we need (or at least they are frequently requested):

1.) Ability to customize mortgage rate and possibly apply a haircut on the rental income to account for vacancy.

2.) Model the tax savings from mortgage interest, real estate taxes, and interest on co-op common charges.

3.) Filter specifically for condo vs co-op vs HDFC vs tenant-in-place

Also a question: we are struggling with how to allow power users to see all the data they need without overwhelming the first-time user. Is there a site you can recommend that does a great job with the power user vs first-time user experience, and is fairly data analysis heavy?
