Yes but not what you're providing...under the kitchen cabinet will be instructions on how to restart the garbage disposal, etc. 

Sometimes there are small things that you can do like add dishwashers, garbage disposals, fresh paint, new light fixtures, or a more stylish flooring to increase rents.

5) Kitchen sink disposal stopped to work and our regular maintenance person found coins inside it.

With 90k at your disposal, instead of tying up 90k to control and participate in appreciation on 450k valued real estate...  

I currently work full time as an IT technician and would love to help, if you have a business or current projects that require computer skills, I am at your disposal!

Ive been pitched by various people calling themselves "syndicators" but I find their supposed deals are just repackaged deals from other true syndicators who actually acquire, manage and dispose the asset.     

If it won't cash flow with 75% LTV, then probably not and should be disposed of. 

If I had 250k at my disposal, what would be the best way to build my passive income and help the most people.

I like your idea, however, just a bit of the devil in the details.Best, TerrellTerrell,  I do provide all the appliances aka Washer, dryer, garbage disposal, dish washer, refrigerator, and stove.In the higher end 2 units i have the appliances are brand new (Got a great deal on them from home depot) and the tenant is responsible to deal with Home depot when it's under warranty.

It is cheap and disposable--does not last more than a year or two, at least in CA.
