Start with a list of cities with a metro population greater than 1M, and evaluate each city against all the additional criteria.

Hi JamieAre there any specific areas/markets where you will work with investors to include additional properties as part of your inventory?

Additionally, is it reasonable to request the current leases and what I believe is called the rent rider form (please correct me if that's not a real thing) prior to making an offer?

If you are purchasing an investment property, and intend on using for investment purposes only, not personal use, it might be possible for you to rollover the TSP to a Self-Directed IRA and purchase the investment property through this type of structure.

Additionally, checking local listings on Zillow or Craigslist can help fine-tune the rental rates in that specific area.

At the current price, adding the additional lots would make them about $30,000 per lot, depending on the price of the additional utilities that need to be added. 

Also, make sure there aren't additional restrictions on the property condition, compared to a conventional loan. 

Be sure to have a detailed discussion with your lender to confirm compliance and explore all available options.Feel free to reach out with additional questions—I’m here to help!

Aside from that the biggest value add areas I see are as follows: Kitchens, Bathrooms, decks/patios (if added), additional rooms/bathsKitchens and bathrooms tend to be the go-to, but all of those can help you get the most bang for your buck. just keep in mind that if the area is already of high quality, then it may not be the best area to spend the money vs something that is blaringly in need of an update.

Make sure to have a security deposit that takes into account the additional risk.
