An umbrella policy is relatively cheap and I feel secure in doing it this way.  

Cheap House = Expensive HeadachesWhy buy 5 units in what sounds like a D class area when you can make the same cashflow with 1.5 units in a safer area with quality tenants.

I live in Phx,az and recently friend of mine sold his bank (ex bank of america) literally as is and profiteed $300k  , he purchased it right out cash last year (I think) and it was in real bad shape in a shady part of town,  before him taking possession of the bank  homeless people where living inside it an using the bathroom anywhere in the building, he put maybe less than $5k in just cleaning it up and just a couple of days sold it.Basically the idea is to find super cheap homes in ****** conditions but the price is so cheap that you could still make profit by selling as is, investing as little as possible..

Money isn't supposed to be that cheap.  

People go there because it's cheap.

While borrowers expect transparency and efficiency, lenders strive to provide upfront explanations and support to ensure borrower success and foster lasting relationships.In the lending world, there's a common understanding that achieving all three qualities—fast, easy, and cheap—simultaneously can be challenging.

$450k is pretty cheap for a Cali so maybe it works as rental (don't know the strategy here) but rental cash-flow could take years to equal $225k tax free. 

I am cheap, but everything looks good and functions well- most important if you are renting it out. 

If your agent isn't knowedgable they can over or undersell you and that will affect your costs.An umbrealla policy was reccomended to me by my agent (a family member) and in general I think it is a really good idea and usually a  pretty cheap option for risk mitigation.I don't have a specific company to reccomend but hopefully this was helpful.

But I also learned-reluctantly- I need a mentor, and that's not always cheap.
