This approach can be more effective than excess liability coverage because if an excess policy is exhausted, the remaining properties may be left unprotected.

The U.S. housing bubble will burst.The only variables are how and when Housing Bubble #2 will burst.The incentive (lower mortgage rates) to commit fraud by claiming to be an owner-occupant rather than an investor has pushed mortgage fraud to levels that Federal Reserve researchers declare "rampant."

Guys that know what they are doing can roll off a 12x12 room in 15 minutes and cut in a typical room in less than an hour.

Over a 10 year time horizon I am projecting that cash flow, combined with appreciation, combined with tax benefits will do much better than an S&P 500 index fund.

You will care about and take care of your property more than an agent, property manager etc. who's over a thousand miles away. 

If you are selling a vacant single family home, I would think a buyer looking to live there would most likely value it more than an investor would, so if your marketing is more focused on attracting investors as an income property, I would also market it/list it as a single family home.

Have had two instances of the furnace in that same unit going out, both times cause a bird flew into the exhaust and lodged its head into the fan.- AC in my unit that we lived in went out twice while there in year 1, maybe year 2, spent about $800 to have it pressure tested (lesson learned here most home warranty companies are garbage and do not cover testing your HVAC so idk how you trouble shoot it without testing it, but the testing and refrigerant are not generally included) chased a leak for a month and ended up having them replace the line-set to the system for $1400.- AC in the other unit went out a year or two after that, was not a big issue, just needed one of those jump starter things, and some refrigerant, but was about a $800 fix to get it done on a weekend.- Roof vents were not secured correctly, so that lead to a leak into one unit when it shifted, was about $750 to get the vents secured and have additional ones added to bring it up to proper number.- Still need to get the gutters done, they need cleaned and one of them doesn't drain as it should.- Main water line and entire meter popped off the main supply line and had an unimpeded 1" water line dumping into the basement on mother's day, was about $1400 to fix, and basically an afternoon of waiting around for city and fire dept to turn on/off water at curb.
