Ideally, I would like to buy a turnkey rental property within the next 1-2 months.I have a religious prohibition against taking on any loans/interest/dealing with banks (I can't use leverage) etc. so I am limited to the 80k in cash that I have.How and where, would the experts on here, recommend I invest my 80k?

Appreciate your "spiritual" or "religious" comment and advice, but keep that for yourself as I keep mine for myself and make my judgement.

With the new tax rules that amount is capped and many people in California will wake up to a very rude awakening in April/May when they expect a tax return payment and instead will be asked to pay additional money to Franchise Tax Board and IRS.With all that I think you would be better off to consider turnkey investments that cash flow from the start in locations with continuing economic and diverse development in more affordable cities and states.

while that is an awakening for you, its a chance to feed you some knowledge in this January 1, 2019 about mobile homes and the moving parts within them.1st of all, MHPs in CA are a major pain, and analysis paralysis isnt always a bad thing, in this case run from that deal. here is why........that mobile home is  POS.2ndly you i can tell from the info you posted that you dont know about Dodd-Frank or the Safe Act of 2009 which is harsh laws that come down on investors carrying financing to unscrupulous low income buyers of would be mobile homes in parks or on land. 

Something is up.This is meant to awaken those who have a 401(k) or IRA in the market to consider other investments which is the cautionary approach to preserving wealth.

I left my media executive job in LA and co-founded a media advisory firm, and it's been a BIG awakening at the new financing challenges it's created, even with meaningful income for our first 18 months in operation.

My only concern is the renter tripping GFCI's and calling every time - I guess it is easy enough to just tell them to reset.I am handy enough to do the GFCI replacements - when I was a teenager, I volunteered on projects thru my religious organization in the electrical department.

With my last few years in Indiana I got very interested in real estate investing and read everything I could while listening to bigger pockets podcasts religiously. 

Besides reporting to the police  I would reach out to your local religious organization, local politician, to see if any community watch dog  drives are existent or being organized ..
