Mortgage rates and PMLs are 8-12% plus points right now so the deal has to be a low enough entry. 

Most mortgages say the lender has the right to buy homeowner's insurance for you if you don't prove you have it.

Hi,As someone that moved from CT to SC, I will tell you property taxes here are very low, you would feel the same coming from NY. the 4% for primary and 6% for a rental, at least in Charleston County where I live, is not 50% more it is really x3 more , but still low compared to NY, so while others from SC may see it as high, you may feel it is a bargain.Not only that, being a landlord here is much easier, you actually have rights on your property, which is not really the case in NY/CT.I read your mortgage rates are in the 4's, expect to pay in the 8's right now, so unless your plan to pay cash, which, I personally am not sure I would do for an investment, many reasons for that, it is going to be very difficult to make money. if you are looking for appreciation rather than income, it may make sense.Hope this viewpoint from someone that moved a few years ago from similar place is helpful. 

Overall, for every type of property....I would say that keeping up with proper maintenance is what most people neglect.

@Anthony Sigala that "Rule" was created for mostly Class B properties BEFORE the Great RE Crash of 2008-2010.Values after the Crash dropped so much, that it could also be used for Class A rentals.Values are now more than their pre-crash highs, so the rule now only applies to Class B & C rentals.How are you identifying Class B & C submarkets in your area, so you can properly apply the rule to the right rentals?

However, the rental value this area is very low compared to the Home values and mortgage rate.

Quote from @Louis Hamilton: The property is worth around 800,000 and has no mortgage on it.

I am bullish on the FHA 203k and home-style renovation loans that allow you to leverage the cost of your renovation as part of your mortgage, which is just an insane deal, in my opinion.Do you have a specific area where you want to purchase?

So, maybe do 30-50% down, for better cashflow and make sure you have reserves for mortgage payments in case there's a rental market dip in the future.DM us if you have any more questions:)

Maybe a mortgage lender can chime in.
