Look into local tax incentives and financing options, and reach out to local real estate groups or mentors to better understand the market.Good luck!

What are true returns for comparison, before or after Income taxes? 

Some factors to consider are appreciation and tax strategies.

Enough immediate cashflow to balance out the mortgage, taxes and insurance.

I noticed that the previous owner let them pay half the security deposit and the other half later, which is a red flag.

That doesn't seem right about having to chase your money - but would need a lot more info to provide a better opinion. also are you investing in one property and is your name secured or you giving an unsecured loan? 

Consider all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

I've been buried with tax preparation and a couple projects, so BP moved from the back burner to completely off the stove!

. - Taxes are on the higher side at $6,000 yearMy Numbers: $115,000 putting 20% of my money $23,000 and finance the rest with total expense of $1,834Monthly expense numbers: Future Maintenance 13% $273 - Vacancy 5% $105 - Property Insurance 5% $105 - Property Taxes 23% $500 - Property management 10% $215 - Office/Travel/Legal 4% $84 - Mortgage 26% $552 - Monthly Cash Flow - $316 per month or $3,792 per year so Cash on Cash = 17%I think this looks like it is a deal worth doing and I also believe I can bump the total rent up by $50 each tenant which I think make it even better.

So many variables can turn a deal sideways from 1 hour to the next - i.e. inspection findings, title issues, contracts, financing issues, taxes, dept. of buildings/local municipalities, etc.I'm glad to hear you made it through the challenges, and it sounds like you'll be able to leverage this experience as you grow your portfolio.All the best to you along your journey!
