@Tim Bartel,With a 4-plex, you need to think about quality of life, for the tenants, and also for the animals.     

Additionally - if you have any referrals for quality agents in these areas, i'm all ears.Any and all help is appreciated.Thanks!

Generally speaking you would want something at least 75 units, so you can implement some quality full-time property management. 

My long term goal is to have a portfolio of rental properties in my local area through the BRRR method that could allow me to retire, whether or not I choose to. 

Matthew,I might be able to help with a quality PM, but I need to know where the properties are located.

2) What methods do you use to determine a comfortable number pay the lessor per month while leaving enough  wiggle room to pay mortgage, cover for vacancies, repairs, taxes while having a good cash flow left over with the intent of saving this to use for the 20% down payment when the option is exercised.3) Would you pay for an inspection up front before the contract is signed, or wait until it's time to exercise the option?

My question is that we are really looking for flips at this point but due to potential cash flow of this property, which i have yet to analyze, do yall think this could be a good candidate for the BRRR method or are there things i need to consider first that i may not have thought of yet?

Does anyone recommend a quality property manager close to this location?

However, we want to refinance right away, pay off the LOC + repairs, and take some cash out to purchase more properties (BRRRR method). 

Outside of numbers I will also look at the area and see what the unemployment rate is and if the median income can support 2.5x's the average rent amount I'm seeking after the purchase - I also look at the competition's rates and quality.
