If I spend 500,000 6-600,000 here in La county for example, I will get a undesirable neighborhood, crime, low income, gangs, uneducated neighborhood and a house that most likely was built in the 1930's and outdated.

He has put a NOD on all three because lendee was late in April, making their properties even more undesirable to potential buyers, hindering their sales and is now considering on lending more for the condo's rehab to get it on the market.  

How about Peripheral Bay Area markets like Tracy, Livermore, Hayward Hills, or even Sacramento?

He inherited a bit of a mess from the previous owner (bedbugs, undesirable tenants, and deferred maintenance), but we're getting things straightened out. 

The real beauty of property management is that all of your clients are real estate investors and that leads to all sorts of peripheral business.

I've worked in a technical support position for several years and can fix a and assist with Apple computers, iPads, iPhones, software, networks and peripherals.

But I guess I’m assuming a $10k mobile home parked somewhere nice is worth more than one parked somewhere undesirable.

While that price tag is appealing, the trade off is often a lot of tenancy issues (including the whole Section 8 hassle with housing authorities), huge rehab requirements because of long-deferred maintenance etc,  as well as lost equity because homes in these areas are unlikely to sell for any substantial amount no matter what condition they are in, simply due to the neighborhood - so any refurb equity is basically cancelled out by the undesirable location and the condition of surrounding properties, crime rate, etc.If you do decide to go the TK route, I have a lot more to say about the questions you should be asking of any provider you consider (and if you look at any of my past posts, I harp on this point quite a bit).

There is always a 'range' of rental prices and the more you can keep your property at the top of that range, the more likely you are to have tenants who don't want to risk losing their place by missing their rent or other undesirable behaviour.

it looks the "deals" are more in undesirable areas.
