I cannot put their info in chat due to rules of this site but if you do a business search you should get a valid address for both to send a letter and they will respond.

This lets you take fullest advantage of the primary residence exclusion and restart the clock on your next primary exclusion (although the rules are a little different when you convert a property). 

Any rule of thumb for that?

Forget that "50% rule".

@Cathie Kovacs There are a lot of tax implications when investing in real estate via an SDIRA.There are strict rules and guidelines as well as possible tax liabilities (UBIT, UDFI) depending on the investment.I'm biased, of course, but a CPA is a necessary team member if you're using an SDIRA to invest in real estate.

Also, the rules can also be different when you want to get rid of a roommate (legal term = "lodger"). 

What is your rule of thumb on rehab cost and how do you determine your cost? 

The rules of an MLS usually say that when a buyer has been identified and the property is no longer available, the status needs to be changed, which is probably what's going on in your case - the property might still be available, and the buyer may or may not close, so they don't want to shut everything down, but also don't want other agents to spend time on a deal that might not be available.

The 1% of purchase price is a good rule of thumb, but you might want to consider seeing what similar units on the market are renting for in that area.
