@Larry T. totally get it. 

If not, why have a 401(k) at all and not entirely rely on social security?

That makes total sense to me. 

I should also mention that I paid $1,000 towards my buyers attorneys fees and in addition he charged my buyer $850 for a grand total of $1850 in closing fees...so I am pissed off  that he took advantage.

Do not rely solely on your PM- they are not CPA's!

What is Estimated Principal Reduction and why is it added to my total return before taxes? 

(*In this context, “eligible investors” must have had a minimum of $75,000 of income personally in the past two years; income of $125,000 when combined with a spouse; or $400,000 of total net assets either alone or with a spouse.)  

Suppose you have a subject property with a 105,000 sq. ft. lot and existing improvements for which you estimate the reproduction cost new to be $2,500,000, physical deterioration to be $400,000, functional obsolescence to be $50,000, and external obsolescence to be $50,000.If you have information on a comparable lot of 110,000 sq. ft. which recently sold for $250,000 and the only adjustment is $1.75 per sq. ft. for the difference in lot size, what is the indicated total value for the subject property.

The agent I bought my primary residence with (totally different market - L.A.) is awesome.

It has a total of 5 bedrooms, 2 full bathrooms and kitchens.
