A 100$ a door to me is a waste of time and I’ll do a vanguard fund before I answer evening phone calls about a mouse  and change out light burnt bulbs Many newbies are scared to do multis right out the gate due to lack of experience .Multis often cost more .they are sometimes harder to get loans on from a lender .some people prefer appreciation with the  single over cash flow of the multi .Some people want to be able to get out  ( exit strategy) easier if they fail . 

So my question is I am planning to rip out the worn/stained carpet and lay down a pad and nice wood look vinyl floor!

6 acres seems to me to be a couple of city blocks (in many areas).Maybe room for 2 churches, or a small hospital, or a big truck stop, (all zoning issues probably).A big strip mall with pads and major anchor tenants?

But 20-25% padding is reasonable.

And of course, my personal crash pad if the city inspectors will buy off on it.

I could even put RV pads in the back field for summer.. 

I am thinking about putting in smart locks with key pad entry.

Park improvements (utility lines, roads, mobile home pads, etc.) are often allocated 65-80% of the total purchase price for tax purposes.

In the month-to-month case you bring the tenant to court for X offense, then they turn around with pictures of damages or mouse dropping, then this all turns the tide back to the landlord responsible to correct the issue first, then reschedule the hearing to a later date on the docket.

Those alerts can also be seen if you mouse over the "Inbox" on the upper right menu bar and scroll down.
