I infer from your question that the only reason the company would hire your son was because he would benefit from doing the work in your IRA held property.

If it looks like a clean deal, I wouldn't do anything until you get that deed signed by all the parties and held in escrow until closing when it can be recorded.

If it were me, I would simply let them know in writing that any alterations must be returned to original condition at lease end or they will be held liable for damages.

The borrower must have held legal title to the lot for at least 6 month prior to the closing of the permanent mortgage for cash out. 

I would not pay any tax because it was held in a Roth account.

This feature comes with an interest rate premium in most cases; some will provide a forward commitment up to six months without charging a premium, but the usual cost is 3-5 basis points per month when the rate is held beyond a 90-day period.

I need a good insurance broker to insure a vacation rental.  So far having trouble with UWs who don't understand the scenario nor Hawaii. Can anyone help? 

I held off on the modification and found more qualified renters who like the property as is! 

The reason this CAN (not definitely will) be done is because some of these pieces of land are inherited or have been held onto for an extremely long time and people simply just want to get rid of it.

It is getting more popular and those who held have made some crazy gains.
