Inventory in Austin dropped to an absolutely insane 0.9 months with a 29% decrease in active listings compared to the December prior.

According to Zillow and my own research in my area prices are stabilizing even decreasing a hair.  

Maybe tell her that the amount she will get paid will decrease each month until she has the right to sell the property? 

Here are the specs:6 unit brick multifamily Apt building-priced at 569,000- negotiated down from asking 600,0006-2bd/1bth apts currently does 4700 per mth-rent currently about 20% under market at the start of due diligence was 100% occupied-That is what I based my offer on building performing at 100%tenant just gave his 30 day notice -so before closing the building will have 1 vacancy performing at 84%The inspection also turned up 15k of safety violations I believe both are points of renegotiation-I'm just not sure how much is my question-I was going to ask for 15k of a closing concession to cover the safety issues-but how much is considered acceptable/reasonable to decrease the price for the vacancy?

Since you own more than 4 units it's a commercial property so increases in expenses/decreases in expenses will drive its value up.

If your strategy is different, then below will not work.I invest in apartment buildings where I can "force the appreciation" or add substantial value by increasing rents, decreasing expenses or preferably both.The problem for investing for the long term and focusing ONLY on cashflow is that the investor's money is stuck in the project a long time.And of course, the problem for investing for appreciation is that it's speculative.Since I only buy buildings I can add value to, the market is IRRELEVANT.

This is because you purchased your home with a primary home loan...and those usually have much better rates than investment properties.When you refinance, you will remove PMI, which should help decrease your payment some.When you refinance with a conventional "cash out" loan, the maximum you will be able to receive is 70%....so around $10,000 cash out.

Definitely not decreasing!

They are such a great way to decrease your expenses while building wealth at the same time. 

I hardly needed any other money since the 1st building, constantly leveraging off that equity, and then the equity of the 2nd, 3rd, etc... to eventually now, buying $1.5 Million buildings all cash in LLCs.I'm not saying that this will be your future, but it's a very compelling future if you visualize it well.Don't forget that if you used a fixed rate Mortgage, even if your property does not appreciation, the Mortgage balance decreases over time, and your equity builds up.That equity then seeds capital to your next deal.
