In particular I am seeking help for the following;1) "Provide an evacuation plan (shall include Site address, floor plan//site map, escape route(s), meeting placeoutside the home, emergency number 9-1-1).

I do like real estate, I have a great eye for design, but would hate to have to evict someone—that would be my worst nightmare, so I’m not sure I’m cut out for being a landlord (although I would fully anticipate having a property manager)Is option #3 a far inferior option compared to keeping our expensive house in expensive city as a rental and only having to deal with one property that gives us great appreciation in 10 years ?

But for straightforward setups, you can actually form an LLC directly on the PA Department of State website yourself, and it’s very cost-effective.For larger portfolios or more complex structures, some investors prefer going through a real estate attorney to ensure their LLC is set up to maximize tax benefits and liability protection.

As you venture to try and find what cities/areas to buy in might I suggest this resourcehttps://www.areavibes.com/This is a great website to get an over view/starting point for what the neighborhoods are like.

If you feel you really want something more special for a nicer flip or something, get a design consultation from someone local who can give you a whole color scheme for the house that will make things pop. 

I came across this guy Kris Krohn on instagram and have been going through all is social media and websites.

Do you use forms or what is your design?
