There is a package of duplexes for sale in North Dallas (Richardson ISD). They are currently overpriced at $380/$390K. Worth keeping an eye on to see if owner would take lower amount ($340s) for a package purchase.
All are 3 bed/2 bath units with garage. Rents at or trending $1500 per unit. Street rents very well. Keep an eye on them.
Let me know any interest. There are a couple of different package opportunities for 2-4 unit property. Overpriced but who knows with the right offer and buyer. Let me know.
