Most homes I'm finding, including in general a 20k rehab, are around 65K.  

Tough market for cash slow, but appreciation good in certain towns including mine---high costs, though.

Experience, accessibility of support, protecting your personal data, how long a firm has been in business, etc. are things you will want to include in your mix.

I'm not an anti-stock market guy by any means, but I recognize that attractive long-term returns in equities will include a lot of volatility along the way. 

Other websites including Yelp and even their facebook page have enough negative reviews to have me cautious about them.

Because Saturday and Sunday only amounted to two days, and you would have no business-related activities on these days, the fact that you had to stay until/through Monday to finish the seminar, still means that majority of the time there was spent on deductible activities - thus whole trip, including air and hotel is deductible.

You can negotiate with the seller to do cash for keys because "TECHNICALLY" you are purchasing the property with all assets and things attached to it, including tenants.

Your appraisal report will include a separate rental comp/market rent rate, etc, report.
