So he needs to be more ITM than  the 1.25:1 ratio.With that said, to answer the question-- figure out your debt or income.

Owner occ developments there is no value associated to the income approach so these props generally speaking will appreciate a lot more as the neighborhoods are much more desirable. builders the last thing they want to do is sell to investors if they are creating owner occupied communities.. rentals degrade the neighborhood and they will be sabotaging their own values to allow a bunch of investors to buy and rent out in their communities.So when you buy new builds keep in mind if its a build to rent community they will NOT appreciate like owner occupied neighborhoods.. might be best to find something already 3 to 5 years old where the stigma of renters dies down.. that would be best to protect your investment.

I’d check the local market to see if there’s a steady demand and compare the potential income with what you're making now to see if it's worth it.

Correct - Track all your income and expenses.The bookkeeping will determine whether you are profitable or not.it will also be good to compare from year to year your income / expenses to see what expenses you can potentially try to limit.I.E.

Offset today’s income with depreciation.

They’re fully renovated (or in good condition) and often come with tenants already in place, so you can start making rental income right away. 

Which is why I pay more, for less cash flow in highly desirable areas.In high income areas, rent is a lower proportion of income so therefore your tenants have a higher capacity for paying higher rent because rent is less than 20% or even 10% of their income.

@Anshuman ThakurThere are some very good advantages to investing in Nevada, low property taxes, no income tax, and landlord friendly.

The calculator estimates that operating expenses are equal to 50% of the monthly income.  50% is a rough guide. 

Many voucher holders also work and so sometimes they will have a higher amount to spend than someone who doesn’t work because they can pay up to a % of their net income from the HA’s calculations, often 30-40%.
