I am seeking good ROI analysis tools (spreadsheets, calculators) for evaluating multi-family live-in unit (3 or 4 units) that I am planning on purchasing in Orange County or the Inland Empire in Southern California, over the next few months. 

Both have seen significant growth as populations have moved north seeking more affordable rental options. 

Hi everyone,I’m a local investor from KY who has a 30-unit apartment portfolio under contract in Toledo, OH (3917 Airport Hwy), and I’m looking for structural advice as I enter the final due diligence phase.The Deal Snapshot (For Context):Asset: 30-Unit Stabilized Multifamily.Price: $1,425,000.Performance: The property has a verified 9.27% Cap Rate and generates a very safe 1.55x DSCR.Equity Needed: $413,250 (includes reserves).Returns: 9.06% Cash-on-Cash (Day 1).The Ask (Structuring Advice):I am seeking one strong Joint Venture (JV) equity partner for this acquisition.

Congratulations on your purchase! 

I'm self managing and therefore need an online rent collection portal.

Quote from @Christopher LeBlanc: I'll jump on this bandwagon.

It's a lot more hands-on, of course, but by rehabbing the property, they "force" the equity themselves instead of just waiting on the market.The rehab is a medium to high including some high ticket items on it.When it comes time to refinance, even if they can't pull all of their cash back out, they've often created their 20% equity stake (or more) through the rehab.

The only blemish is that a five year tenant recently moved to monthly instead of their typical annual lease.I'd like to preserve the current rate on my mortgage, which likely leads me to HELOCs, HELs and possibly 2nd lien DSCR, but I am open to any options.Given that information, what do you recommend? 

@Stephanie DeppeHere's some helpful BlogPosts here on BP that will guide you on some of the different options. 

It really helps have 50 sets of eyes on each of these investments, for analyzing risk.
