Purchase price: $8,000 Cash invested: $2,000 I purchased 2.5 acres of Raw Land in Joshua Tree, less than ten minute drive from the park and downtown area in 2018.Purchased via seller financing.2k down with monthly installments to pay out rest.Current similar lots are selling for around $65kI plan to hold long term Would eventually love to develop something on the land-either an art park or residence.

However, government officials, pandering to populist sentiment, hold landlords to standards and responsibilities far more restrictive than any other business.  

Your passion for real estate and diverse interests in wholesaling, fix-and-flips, and RV parks will be a great way to scale.

But I would contact the owner of the park (assuming you're not buying the unit from them) and ask them. 

It is in North Park, developing fairly quickly but nothing I would call 'luxury'.

@Vito DiIennaWhile I have not had to get a Letter of No Objection myself, if I had to do it, I would go right the the DOB, go into the Office that you can get an official Cert of Occupancy and ask them what is the procedure to get the letter.Normally, you will need to provide evidence.
