Justin, You have several questions, but I'll start with the first. Investor payments will depend on your business plan for the property and defines your criteria for the property.
If you are looking to purchase a property strictly for cashflow, you would look for something stabilized (low vacancy and delinquency) and profitable. These would provide predictable income which could be paid out as distributions (quarterly or other) year to year.
If you are looking for a property that has the potential for increased value you may not have sufficient profit day 1 for distributions. The most common ways to increase the value of an apartment are increasing rents in the event they are below market or improving inefficient management, or both. Both will increase the net operating income of the property which will increase its value, and you could sell or refinance to capture that increase.
A couple examples:
I have a 40 unit property purchased with a few partners last year that had below market rents and inefficient management. We are in the process of renovating the units, fixing the deferred maintenance and making some improvements. We didn’t plan for significant distributions for the first two years as we do all this work, reduce vacancy and get rents up to current market. We will consider sale (very hot market) or refinance and hold when done with the work.
I am a passive investor in an apartment syndication which cashflows to start and has some opportunity for increased value. I receive quarterly distributions while the operator works to unlock value from increasing efficiency and make modest rent increases. The business plan for this project is to sell year 5 at the increased value.
