If you climb out of the 7th century, some might!, but I doubt it.

There are no guarantees....

Iran is a lawless country. IRGC can take your land at a prime location at will  using the excuse they use all the time , which is we want to build a mosque.

Don't be fooled.

فکر خوبی است، فقط باید کمی اعتماد سازی کرد. اول آن املاک و دارائی ها که به زور از مردم گرفتند به صاحبان اصلی آنها برگردانند و اجازۀ فروش و خروج پول را نیز بدهند تا قدری اعتماد سازی شود و مردم سرمایه هایشان را به کشور وارد کنند. 

That train left the station 5 years ago!

During Rafsanjani and Khatami presidencies (1989 to 2005) and even before the bloody "re-election" of AhmadiNutjob in 2009, an investment in Iran could easily have 10% to 20% return.

Today, such an investment would be very speculative and high risk.

The government of Iran cannot and would not peg the Rial to the US$ at any fixed rate, therefore, even if the real estate market or the stock market in Iran recovers, there is no guarantee in a reasonable rate of return, based on a hard currency.
