Hi Eugene,  I'm a real estate agent with Keller Williams and an investor in the buy and hold strategy, concentrating on small multi units.  

I would concentrate more on investing, unless you are going to open a management company.

Hi everyone, I'm an investor primarily focused on the Capital District, with a concentration in Troy, NY.

We sold all of our prior holdings in 2006 to concentrate on another business. 

Here are some of the pros and cons that I see:Pros:Property management costs would be lower over the life of ownership due to proximity of homes in portfolio, low maintenance flooring, siding, etc.You could build them with more robust systems(HVAC, plumbing, etc) knowing they would always house rentersYour portfolio would be concentrated as opposed to spread all over a geographical areaYour exit strategy would be super attractive if you were to sell as a packageQuicker than purchasing and potentially rehabbing an older property, and accumulating them one by oneYou could sell a percentage of them to recoup a portion of your investment, and rent the rest, which should put you with solid equity from the gateCons:Entry costs and length of time from start to first months rental income for constructionFunding the construction, or finding the right lender to fund such a property/developmentKnowing the correct price point of the finished product, or what the community is lackingLocal zoning or possibly being prohibited to build SFH to rentHigher construction costs vs. multifamily(apartments or townhomes)I know there are many other strategies out there, but as one wanting to accumulate a nice rental portfolio, this seems to be a solid approach.

I'd avoid bleach as you can start to make some pretty toxic gas depending on the concentrations of acids. 

It seems that Andy should concentrate on properties that are not already managed by Property Management companies.

My assumptions going on (with no facts to back any of them up) was that I might need to concentrate on South Phoenix or some parts of West Valley. 

I’m leaning toward multi-family residential properties, as I like the idea of having my investments somewhat more concentrated to take advantage of synergies.

Concentrate on being the "contractor" partner and having rights to workmen's liens which can force sales.
