In a building with 5 apartments, where the average monthly water, sewer, and trash (W/S/T) costs run $75 a month which is about our average, that would equal $375 each month and $4,500 a year.

Cut cable, Starbucks and door dash out.

The other thing your going to run into is cash reserves the DSCR lenders require as you grow they are going to want to see 6 figures in cash in a statement of yours..

however, even with a BRRRR you would need an absolute home run since you're financing 100%. 

Hey AlbertoWe have about 70 doors primarily in Tampa/St Pete/Clearwater area but also have some in Naples, Ft Myers, and Kissimmee.We are pretty much the same as you but I will add some caveats from our experience:January - Definitely good the first week but generally pretty bad the rest of the month. 

Prices are still somewhat affordable around 90-150k per door depending on the area of town.  

The only obstacle I continue to run into is finding funding.

You just need to run all the numbers, and also take into account any Passive Activity Losses (PAL).Make sure you use a Qualified Intermediary (QI) for the transaction. 

I own 7 and manage 100+ doors, primarily STR/MTR.Love working with young people, please reach out and we'll talk.

Run your race and grow at a pace you are comfortable with and keeps you out of trouble with leverage.
