We are developing as RV /campground - tiny homes on wheels - where is your property?

They have a bigger single family home and a tiny home on the property, but there close proximity and shared driveway present functional problems that are undesirable for guests. 

Everyone and their grandma is a realtor, but very few are qualified to produce the results you hire them to do.

I suspect your underwriting will show that RE in San Diego without leverage will not produce the return that you will desire.Note at 80% LTV, the appreciation return is 5X.  5.82% long termappreciation (the rate for this century) * 5 (leverage multiplier at 80% LTV) to the cash flow 4.8% and we get 29.1% return from appreciation. 

The claims of 1hr to collect rent, produce receipts, and deposit checks also seems like a reasonable claim if done physically and not electronically.

The educational system in the U S is extremely lacking in the field of business/economics if someone can write a book as simple as RDPD and have millions of people say that the simple concept of if you save money and invest it in appreciating/income producing assets you’ll be better off than if you spend it on unneeded toys has radically changed their life’s because they never knew of or heard of that concept before.  

There is some but you FB or local event would produce more.

To maximize your tax advantages, treat 75% of the property as rental income-producing, allowing you to deduct expenses like mortgage interest, property taxes, and depreciation on that portion.

Sounds like you're in the scale/harvesting time so I think you need to determine if this property is something you are happy with the cashflow it would produce as well as the time needed to manage it or hire a property manager, or is it time to take the equity and redeploy it into something more worthwhile like a higher cash flowing investment or creating higher equity in the home you buy down here.

Hi, I ordered two ADUs from TINI Living (they're in Spain).
