The whole house needs to be remodeled due to lots of wear and tear and being outdatedI am planning to use a HELOC on my current property for mostly all the repairs.

How can I put them all into one portfolio and just keep adding to them as we obtain more? 

You want to know of any & all problems before spending any additional funds on the property!

They can handle everything from tenant screening to property maintenance and making sure you’re compliant with all the regulations.

They have already done all the hardest work.

I tried Simpli Safe but, there cameras all need wifi to be able to live stream and record.

These costs for most of the individuals are considered personal in nature (unless you have a RE portfolio that is run like a business; see below).

I had two different companies.. one in Oakland CA circa 88 to 92 all investors all private and all 100% of funds for loans put up from the investors. 

If all you are doing is watching YouTube videos, you don't know as much as you think.

I have several multi families on the west coast  ( one that I actually manage my self in California) and it’s just one maintenance reserve fee for all doors , and a % of the total rent usually ( 8%-10%).
