Insurance would cover it, I would pay the deductible, and no assets would be lost.If you are in an area like San Diego where people are more likely to sue, a judge is more likely to find you guilty, and the payout is likely to be higher, then you may consider an umbrella insurance policy.

Also consider an alarm to sound when the sump pump is not working. 

If this is something you're not really interested in getting good at and your ROI requirements are modest, you may want to consider an REIT (Real Estate Investment Trust) or syndication.Bottom line: I'm sure you had a simpler answer in mind, but it's just not that simple.

@David Boroughes hi David did you ever consider an LLC as well or do you recommend just having an umbrella policy?

The disadvantage of crowdsourcing I believe is that you can't leverage it.We could consider an actual real estate property, but we live in Boston where prices are insane so we'd be looking out of state.

I have never made a move without proactively seeking out their honest advice, and they’ve helped me dodge a few bullets and pointed me in the right direction – all of which have paid off.As for “main drivers” you mentioned.I think its important to consider an amalgamation of additional drivers that include good schools, infrastructure (is the county planning and building for growth), local government policy, and economic cycles.

Remember though, a lot of pre-foreclosures are upside down so not necessarily a deal..... could be a short sale, but hen it has to be listed on the MLS before the lender will consider an offer, which means you're competing with the rest of the world.

The business of parks - Mobile home sales and licensing requirements, business licensing requirements, bookkeeping, accounting, taxes, etc.IMHO, mobile home parks can be the most stable real estate to invest in, but make sure to have your eyes open as you consider an investment, as they require a unique set of skills to be successful. 

I would also consider  an airbnb or a flip, but with the current crazy market have not found a good flip. 

. - Flipping is consider an active job as such the IRS treats it as self employment income and not capital gains tax.
