Zero, you can do that yourself unless you are spread out over a wide geographic area

@Farrukh Madaminov Rent default insurance is widely available abroad in the UK and Australia and is just now catching on here in the US.Eviction process varies by state. 

But when I search nation-wide I see banks with 2.2% and higher.

Just like any new endeavor you're going to want to go into eyes wide open and learn as much as you can beforehand.Please look up investing in Self Storage on the internet - lots of articles, videos, etc., or PM me.Best of luck to you!

@Hunter Waterman I've found that for banks that hold onto their loans (portfolio), they vary widely in their policies and suspect you can find one that will do a HELOC on top of an existing 1st mortgage from another bank - though whether you like their max LTV (i.e., maximum allowable LOC) is another question entirely.If you're going with a more traditional bank / institutional loan that likely resells the loan on the secondary market, you'll have a much harder time doing anything creative or "outside the box".

Quick second sidebar, since AZ property info is so open and widely available, I invested in a UPS Store mailbox for a "real street address" years ago. 

This way if it gets to court, you can argue that after much consideration, you decided to institute an apartment complex wide pet fee on all new tenants.

Hi ToreyOn average, you can find MF in a wide range of cap rates, it really depends on the property, where it is located, deferred maint issues, and even number of units - there are lots of four plexes at 4% whereas you can fi d apt buildings at 7 to 7.5%.

Farming operations have scaled correspondingly and what was the family farm of my grandparents is no longer sustainable ... in the areas where my parents grew-up, many "family" farms today are working  6 - 10 sections annually - a task that requires millions of dollars in capital equipment.There are also farmers who are specializing in organic and/or non GMO crops (both of which may require maintaining a wide border strip between their fields and their neighbours crops).There were (and likely still are) two principal ways of renting farm land in that area: a) straight rent per acre/quarter/section or b) a share cropping arrangement with the farmer working the land.
