The PMS around here are pretty terrible, I've worked with a lot of the larger ones in Cleveland and I think they just take on more properties than they can effectively handle and don't hire enough additional employees to make it work. 

I'm assuming architect fees, GC fees, Real Estate commissions, and of course interest on your loan ... but just curious as we haven't really dealt with any of those additional costs for our builds. 3) What market are you in and how is the market doing overall?

Might be an additional cost there.If units are updated, capex items look good, leases and tenants look solid, and there are no other regular expenses besides the 5200 in insurance/property taxes then I like this deal.  

Best to call city hall for the town you are buying in to see what if any rent control rules are in place. see link below if you require additional information and call the Jersey City Landlord Tenant relations office. https://www.jerseycitynj.gov/cityhall/HousingAndDevelopment/...Jersey City CPI chart on recommended rent increases: https://cdnsm5-hosted.civiclive.com/UserFiles/Servers/Server...The state with the highest eviction rate in the country right now is South Carolina. 

To give you an idea of how we approach it, we assume the worst-case scenario right from the start is 9-12 months of no rent, $5,000 in legal fees, and an additional $5,000 in expenses to deal with moving their stuff, putting it in storage, and dealing with health code violations or NOV's from the city during the process. 

In addition to having cashflow to add value and push equity, I still have had decent appreciation.

The plan is to use the heloc to purchase additional properties, and basically brrrr and pay back the balance - then repeat.What I didn't realize is how difficult it is to find a business heloc.  

I've opened two additional LLC's with them since I last posted here.

If you used a loan to rehab your property and find yourself in a difficult position, doing a straight refi (just paying off the old mortgage) will be easier than trying to pay off the original loan and take additional cash out.
