I have since put in new hvac system, changed layout from 1 bed to 2, new roof and full electrical upgrade.

What systems do you need at 100 units? 

I use RentoMeter, as well as our own system to compare with other homes in the area.

People having success with this model are buying within a narrow search criteria (4+ beds, 500+ sqft per tenant, 3+ showers, plenty of parking, no HOA restrictions prohibiting non-related occupants, proximity to major employers etc etc.) and hiring management that specializes in the model and has systems + methodologies in place to account for turnover, roommate politics, common area cleaning, utility costs. 

When I think about rehabbing, financing, property management, and other aspects of the business, it can feel a bit disorganized.I may be getting ahead of myself here by thinking about documentation and systemization, but I'd like to have some kind of mental framework regarding how to think about the different aspects of real estate and how they relate to each other so that I can have a bit more structure in my thinking. 

As you learn and surround yourself with like-minded individuals, you will start to put together some systems, processes, cost analysis, and other marketing research that will help you make informed decisions rather than just "a hope and a prayer".

I worked for a GC that used both buildertrend and internal systems for managing projects.

Dear Colleagues,I need help with a spreadsheet or some calculator for distributing utility bills among tenants in my 8 unit building This is an old victorian multifam and there is just no way to sub meter these units....

Points for something you can add value to but can still qualify for financing - meaning the systems work but everything is run down looking and old.

@Rodneisha White a friend of mine sets up outdoor cameras and a simplisafe system with alarms and cameras inside at every reno/new build property.
