I would agree with your "I'm sure waiting till we are married would be easier". You are about to get very busy and stressed out and I would say focus on each other and enjoy this time in your life. I just got married in October 2015 and bought my first property in March 2015 and its gone well, but I closed more than 4 months ahead of the wedding. You don't say what type of property you're looking for but multifamily can take 4 months or more to close and being gone and trying to close a property or get one up and running would be a hassle. You have to find a property, negotiate price, schedule inspections, tenants have to be notified in advance usually 24 to 48 hour minimum, re-negotiate price, schedule appraisal, notify tenants again, wait for them to send all info to the bank, the bank to review everything, and schedule a closing date usually several weeks out. It can be a long process. The first property I tried to buy fell through because the tenant wouldn't let the appraiser on the property and called the police. Needless to say I moved on before the owner could evict her and eventually sold the property to someone else. Also do you have a management company in place or the business structure and all the leases and documents you need? Is the property occupied or would you have to find a tenant? If you have an amazing deal and the management structure in place I would try to get it closed as fast as possible! If not just wait Good luck!
