I have a pretty large balance sitting in an account with her which included balances From not getting paid the last two months of rental income and  tenant deposits and maintenance reserve funds. 

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.While the rental property generates positive monthly income, the interest cost of borrowing the initial $100,000 results in an overall annual loss.

We always choose low maintenance materials for rehab in our class C/B properties.

Won't be high end but I will spend money in areas where it will be worth it to limit maintenance.

You won't find multifamily properties and the houses are generally smaller (which is great for lower maintenance cost).  

Simple maintenance stuff.  

Common fees will include a set-up fee, a leasing fee for each turnover or a lease renewal fee, marking up maintenance, retaining late fees, and more.

Unless your mechanically handy your maintenance costs will eat you up.  

These options usually involve little to no upfront costs, and the solar company takes care of installation and maintenance.

You just need to make sure you keep up on the maintenance and make sure everything is kept up.I might also have a 3 or 6 month inspection of the premises.
