It should save you more than enough to pay for any renovation.

My tenant has not been paying rent for four months now and refuses to vacate.

This is most likely going to be on you, but if you post any lease language that makes the tenants responsible for paying for or reporting repairs - post it and we will try to get aggressive.

This creates two loan payments ($100,000 of equity and $300,000 on the new mortgage).Key NumbersHome Equity Loan Interest Rate: 6%Mortgage Interest Rate: 7%Rental Income: $3,000 per monthExpenses (management, taxes, insurance, maintenance): $800 per monthIncome and ExpensesMonthly Rental Income: $3,000Monthly Expenses: $800Monthly Mortgage Payment: $2,000ExplanationThe investor earns $3,000 in rent each month.They pay $2,000 on the investment property mortgage and $800 on other expenses.This leaves $200 profit each month or $2,400 per year.However, you have to pay $6,000 interest on the equity borrowed.This leaves you with an annual loss of $3,600.This example shows that while the rental property generates positive monthly income, the interest cost of borrowing the initial $100,000 results in an overall annual loss.

The well serves about 74 properties (some lots are vacant)  of which currently 40 are paying and the owner estimates as many as 18 may be stealing water.

Anyway, code enforcement asked to see the inside of the apartment & i agreed as i was doing some improvements inside like painting etc.....afterwards he nailed a red tag to my wall which i didnt pay much attention to because I was literally unaware of what it was or what it meant.

This is one of those questions where paying a few bucks for professional advice might save you thousands later. 

Who pays for repairs?

Prices might definitely correct themselves over time across the country, but I don't see any projections of them going down 30-40% anytime soon and all the projections I've seen, prices are going up.But with rents being so high, and prices still relatively low, compared to a lot of other markets in the country, my experience in this market doesn't lead me at all to believe the bottom will fall out anytime soon.If you've been in Northeast Ohio over the last 5 years you can see for yourself how much they've built up the downtown and University Circle area and literally have poured billions of dollars into it's medical infrastructure, which is one of the best in the world, creating thousands of high paying jobs and people willing to pay high rental prices.But I do agree with Nathan that it's all about having the right team and property management to be successful in this market. 

Money down the road from a historically steady 10% increase in stocks that you will pay taxes on to collect, or immediate cash flow with tax advantages and an annual appreciation of 3-5%.Feel free to dm me if you would like to chat more on the subject
