Every states have theirs regulations.

Hello Edwin I’m a gc/investor operating out of the Philadelphia Pennsylvania area of the country.I can recommend investing in the Philadelphia area as I know it well and I am finding lots of success here.Strong buyer and rental demand.Lack of inventory ( quality rentals or homes)Typically numbers range from 30-50 purchasing 30-60k renovation budget 150 -175k arv on the lower end and. 80-150k purchase 80-120k renovation budget 235-350k arv. 45-115 day turn around timeLicenses and inspection ( building code regulation enforcement) is reasonable and inexpensive.

Expensive regulations. 

Thinking there could be some regulations on this? 

I've noticed prices in specific areas (where zoning, regulations, etc. are legal for STRS) have definitely inflated (and fast) due to cash investors purchasing in these areas.

Fleas, lice, roaches and other pests are not regulated here and landlords can make their own policies but bedbugs must be dealt with according to state law. 

Check you county or city regulation, each have different laws.

People might have their opinions, but you really want to pay attention to what the regulators have to say because they are going to be the ones coming after you - not other people giving their opinions.

Cities are starting to regulate and tax vacation rentals.

Depending on state laws and lender regulations you could roll both loans together and get a LOC on a percentage of the equity.
