Others recommend tools like Stessa or Buildium to track actual costs and project future expenses. 

In future, please try to only invest directly with general partner/sponsors, not through any incompetent "intermediary".  

Many laundromats take card payments these days, which is very helpful in verifying revenue.Look at the lease terms – long-term leases with reasonable rent increases are important for keeping costs predictable, and can also be important for securing financing.Also, check out the equipment and figure out what repairs or upgrades might be needed in the near future.

It’s awesome to see your passion for real estate investing and your clear goals for the future.

I'd like to add another SFH to the business  in the near future with the main goal being grow the business as fast as possible. 

For context, downtown Alexandria performs super well as a rental market and bringing in $5.5k+ as the monthly rental income if you choose to move out of the househack in the future will be absolutely feasible (depending on the property of course).

I hope we can potentially do future business together!

I will keep this front of mind going into future conversations and negotiations though incase it raises other red flags!

From there, I would like to consider a 1031 exchange in the future to acquire more units.My current property management company suggested that they could handle a mid sized apartment building but I would absolutely not consider them for it as I believe they have overextended themselves and communication is lacking.

This experience will help you prepare for more complex real estate deals in the future.
