Seeking general advice
I am in a bit of a unique situation and am seeking advice from this community. My family owns a majority percentage of two large mixed-use buildings valued at over 1m each in a rapidly developing waterfront east coast city. These buildings were passed down to my mother from her father, and she has not done a thing with them besides collect rent for over 20 years. Both buildings are in prime locations and are completely paid for. I am now starting to get involved in the business and looking to create growth and potentially purchase more property. Where do I start? What would you recommend I do? What should I read? 

Thanks in advance!

In other words over weighting the risk of downtime and retenanting costs against the upside of aggressively pushing rental rates. \n\nIf you want to create value and purchase more property I would review the market rates and any near term lease expirations to find opportunities to sign longer term leases at higher rates. If you're in any primary or secondary market on the east coast retail/office rental rates have been growing consistently (less categorically in office) and you should have an opportunity to push rents.\n\nWhether or not you succeed in that effort, you can use your equity in these buildings to get a line of credit to close on new acquisitions \"all-cash\" which at your price point and this stage of the market cycle can be a dramatic advantage", "replies": [], "depth": 1}, {"id": "dptoxqh", "text": "First thing you should do is get involved with the property management and finances of the properties so you understand the fundamentals of the business. \n", "replies": [], "depth": 1}]
