You can maybe maintain the land for the house you want to keep as half the parcel but divide the other half into half or thirds.You can also just sell off the parcels less reward and control since your mom will have to look at whatever they chose to build but less risk. 

Either you have demonstrated ability to do it successfully many times over or you put up a large chunk of your own cash so YOU take the first loss, not me.Investing is about balancing risk and reward.

The bigger the 'risk', the bigger the reward in some of the other areas.  

@Curtis BidwellIt must be very rewarding for you to have achieved 82 properties and for that you should commend yourself. 

I’ve been told “big risks should deliver big rewards.”

I won't offer more the $18K... too many maintenance issues to reward the current owner.Best of luck!

In a business where few people are 100% honest, those that are honest in all their dealings are rewarded with loyal clients, partners, investors and transaction parties.

Offer the proprietors of those shops a "reward" for any eventual buyer who mentions that shop as referring the buyer.Some other BP links somewhat related to this topic:http://www.biggerpockets.com/forums/312/topics/50809-please-help-need-some-ideas-on-selling-homehttp://www.biggerpockets.com/forums/93/topics/43640-ideas-for-selling-a-wholesale-property-in-a-week

Agreed with Many of the posts - but it's like anything else - the more risk the more POTENTIAL reward....Ex - A company in Harrisburg is started buying block and blocks of condemned props in a pretty crappy neighborhood...

Seems like the risk/reward ratio is in favor of buying now and that is exactly what I am doing (except for the $40k, I'm staying in the $20s)
