These 'devil' screws have additional pieces of metal or plastic that act as anchors and designed to expand behind whatever it is screwed to (drywall, wood etc), to spread out the weight n the hanger or the screw reventing the scrw from slipping out through the hole (and in my case with little chance in hell of ever trying to remove them).

Would investing in areas like Hemet and Barstow, so colorado, have an association with older houses, and possible more upkeep/rehabbing efforts into these property types you recommend?

Tell me if I'm on the right trackUsing a gross estimate - the 50% rule...Assuming no upfront renovation is needed...Your gross monthly rent ($3300) minus 50% (taxes, insurance, upkeep, vacancy, am I forgetting anything?)

I was partners on a rehab/flip house, well really just all cosmetics as the house was just built in 2001 or so, so it didn't need any major renovation work but it did need A LOT of cosmetic work, basically everything because apparently the former owners weren't big on upkeep!

They can be worth their weight in gold.

As a result, nobody has purchased it and the house has remained boarded up......the city feels that once boards are up, and the house is "winterized", they never would need to pay attention to the house again.......unfortunately, trees cant be winterized, they grow and will do bad things unless maintained. city disagreed....eventually a tree growing at a 45 degree angle on their property decided it wanted to fall because it couldn't support its own weight anymore. the tree fell in the middle of the street onto my house, destroying my cinderblock wall and chain link fence.

This will help take the weight of ownership off the seller. 

The same item proposed in a fire access lane that fails under the weight of a fire truck responding to a call, could mean a lawsuit for the death of a person.

I make them verbally allot of the time but I wonder if it would hold more weight if I send a written offer?

My out of state property was not intended to be an investment, its just a hold over from the housing bubble.I use a property manager with all my properties, and yes, I could potentially make more with out using them, but I have to weight what I pay them vs could I do what they do as efficiently?
