These small projects add up quick. 

I own small multifamily units in Texas.

Vs say, buying another small multi with the triplex cash flow?

He's someone I already knew, and he does the work for a small rent discount but he's about to move out and I don't think it'll be so easy to find another qualified tenant without losing a month's rent while looking.Before I bought the building, the tenants were all responsible for taking their own cans to the road and they were collectively responsible for keeping the area clean, but they didn't (and I didn't know they didn't.) 

I’m not sharing it to criticize the site owner, but rather to highlight how small mistakes can cost you money when advertising on Google.

I would search for another small credit union or bank that goes up to 100% HELOCS and try the process with them.

We use it for managing our portfolio of SFRs and small multi's and it handles everything accounting wise for the properties so there's no need for quickbooks.You can also run your property management business expenses through Buildium or use Quickbooks if that's easier. 

I’m in the beginning stages of renovating a small unit in my 4plex.

Looking to absorb at least a small part of your knowledge.

All my properties are in a small regional area so I only have 1-2 people per task I need and I have all their numbers saved in my phone.
