sell third house this time dump half the profit into SnP 500 index fund, other half builds fourth house... repeat until satisfied with stock portfolio, retire at 50option C) Aggressive model: sell house for $600k just keep carrying my primary mortgage which is $2900/month and dump the money into 2 properties and build 2 house at once that would each be worth $600k...?

@Roshan K.Ya I know it looks sketchy and defeats the purpose of the LLC but I figure if I kept the funds seperate and can prove that they were used for business purposes only it wouldn't be so bad as a temporary fix.
