:)        This post should be part of getting started in real estate, one of those old texts should be added as a must read book.  

Going to be adding about 400-600 sq ft.

Call them up and let them know you are an investor, and ask to be added to their buyers list.  

No changes can be done after the fact.(2) Assuming you invest in an entity that then invests in the real estate, the entity has to be fully funded from the get go, i.e. no additional funds can be added after (generally applies to pass-through entities) -- while with C-corp that can be avoided, but then you end up paying corporate taxes (defeats the purposes of the IRA)Of course this is over and above the typical rules of prohibited transactions, etc.BTW: IRA stands for Individual Retirement Account, hence you cannot combine to make a Joint Retirement Account (there is no JRA) --- :-)

A bead of sealant round the frame and wall would help to. 

If you'd like to be added to the email distribution list - then send an email (not PM here) to me.

It could be your contractor is running into finding a matching unit for your wall sleeves and then he would be adding extra labor for having the custom fit these into the wall.

Friends/partners can not be added onto the loan.

I will be adding the debt service payment "below the line" and this will include the principle and interest, so I don't want to count the interest twice.  

@Ryan White I was told by mortgage folks that 75% of the remaining tenant rent would be added to your qualifying income.
