What safeguards should be put in place to make sure your payments are accepted?

My second concern would be collecting the rent each month and my first concern would be to safeguard myself from being raped and/or murdered at 4am.

@Jon Klaus, there's a huge difference between simple environmentally sensitive portions of a parcel, and hillside lots in the coastal areas, where we have earthquakes!

Safeguard; make sure your worst case is that you finish at a price that you could sell it to another investor and make a little.

I'm not sure if he knows this but negotiating, sensitivity, persuasion, listening, etc. will all come into play.  

When we build term leases we have built in safeguards for the properties cashflow.

Most people are very sensitive about giving out any information when they are going through such stressful times.

You can sell the house after 1 year from purchase.The 203k loan is an incredible opportunity to buy a house and fix it up to your own taste with the banks money and with safeguards in place to protect you if this is your first rehab.I would highly recommend it. 

@Yashar Ebady You can run your analysis through scenario and sensitivity analysis.
