I buy and hold but only mutli-family to get some ecnomies of scale with upkeep and management.

Therefore, these other things would likely be impacted as well:-  Taxes would likely be lower-  Insurance would likely be lower -  If the property were smaller, capex would be lower, as would turnover costs-  If the property were in a worse location, the standard finishes would likely be cheaper-  If the property were in a worse condition, the standard of living/repairs would be lower-  Property management costs would scale downward by a linear amount to the rentAdd up all those savings, and you'd find that you'd likely save $300/month between a house that rents for $1800 and a house that rents for $1200...

To echo what Evan said generally the higher on the discomfort scale you get, the greater your reward.

I chose to start and scale a syndication business, which is a different level of commitment than taking on just one part of active investing.

At scale you will NEED them to have signed and initialed everything along the way because sometime, somewhere, someone is going to say that they never saw X or didn't know Y and you'll want that simple initial as suggestion otherwise. 

I already own 8 rental properties and looking to scale up...I would definitely agree with Jeremy, it is all about the team you build!!

We are trying to scale that to 200 in the next 12-24 months. 

As @John Warren pointed out it really depends on the type of property.It's common for property management to charge 10% of gross rents for SFH's and small MFR's.As you get into larger commercial MFR deals that number will drop slightly due to economies of scale.

I'm very limited as to how much capital I can have, but I want to eventually find a way to use rentals to scale my income and get off of disability entirely.

One of the strategies that helped me scale was buying properties out of state working with turnkey companies.
