It's known investment of 20% and above is Ponzi and would be very fast liquidated.” where in the world did you come up with that?

Likely, these off market properties will move fast so being fast is key.

Quote from @Jay Hinrichs: I invested in a winery/wedding venue at the end of 2023 because I needed a quick tax strategy and couldn't find a property fast enough.  

Ultimately, it depends on your goals (low rates, fast turnaround, etc.).

Utilities altogether is about $250 a month, internet is $90 a month for the 1T fiber (we want fast internet for 6 people), 5% vacancy, Lawn care $120 a month, Pest control $30 a month, and we do bi-weekly cleaning of the common area at $200 a month.

So spend NO money on advertising and use that money to make our product stand out.. this has led us to raise our prices Far above our competition more than makes up for it and we sell them as fast as we can build them.. for us thats delivering 2.5 homes per month.
