I am assuming here, but if it's been on the market so long, it's priced too high for it's condition. 

If they have a good interest rate it might be worth looking to see if you could assume their loan to take advantage of the lower rate.  

The main reason I ask is because that is significantly below primary residence mortgage rates let alone any investment loans, if you can get rates like that I might need to make some changes on my end hahahTo answer your original question, assuming all else is equal long-term fixed rate debt is valuable. 

Assuming your cash flow is there, you could probably support refinancing the portfolio between 60% to 70%.

@Danth Aman I'm assuming you're doing a general home inspection?

@Eli Fazzojust curious - i am assuming your NY rentals have debt on them. 

@Jennifer Fernéz I run sum numbers for you with our tool, see comments and pics below before refinancing and post refinancing .Financial Breakdown: Purchase Price: $200,000 Mortgage (LTV 80%): $160,000 Interest Rate: 6% (30-Year Amortization) Mortgage Monthly Payment: $959Upfront Costs: Down Payment (20%): $40,000 Closing Costs (3.5%): $7,000 Renovation Costs: $15,000 1 Month of Carrying Costs During Renovation: $1,548Total Upfront Required: $63,548Year One Rent: Monthly Rent Income: $2,000 1 Month Rent Losses during renovations (-$2,000): -$167/month distributed over 12 months Total Rent Income: $22,000 per year => $ 1,833 per monthMonthly Expenses: Mortgage Payment: $959 Property Tax (Assuming $3,000/year): $250 per month Property Insurance (Assumption): $100 per month Utilities (Hydro, Gas, Water): $275 per month Assuming 5% Vacancy: $92 Assuming 0 % Repairs & Maintenance first year because unit has been recently renovated Total Monthly Expenses: $1,676Monthly Net Cash Flow: $157Post-Renovation Refinancing Strategy after 12 months:So far, we’ve purchased the property, completed renovations, and rented it out.Next, you can approach the bank for a refinance to consolidate a portion of your initial investment into a mortgage.

I got a notice in the mail about the tenant's gas and electric being late again, Im assuming they paid that bill instead of paying me because rent is now 18 days late.

. $7k sounds more reasonable but I think setting 5 to 10 years for you and your sister to reach Financial Independence and quit W2 job (assuming you also have W2 job unless you own a business or are a real estate agent) is really challenging.
