After half a lifetime of working and saving and investing in index funds while renting, im ready to make the jump into a new asset class.Looking to owner-occupy a multifamily in the city of philadelphia and hopefully pass a portfolio on to my kids someday.open to any and all advice!

Analyze the property's income potential and expenses and see how it shakes out while you live there and when you eventually move out. 

MTR is less spend on furniture, less guests, and at that price point for a buy, will likely make more money and have less upkeep and management.

And I have access to value add and multi family properties if you are still looking.

They are subject to liability if someone sues, and their license is subject to discipline or loss of license if you violate rules/laws and get caught.

HOA and insurance costs as low as possible.Can you suggest a few good cities in the FL with lower vacancy rates and close to nature/activities?

This creates a lot of buzz around the property and has everyone and their grandmothers talking about it!

But if you are driving for dollars and looking for a home for yourself, you want to use this strategy:Write a personal letter to the homeowner and explain exactly what you are looking to do and why you are sending them the letter.

Google search gives me these super wide ranges and mostly talking about adding a bedroom in a SFH, which I'm not sure if applicable to this situation of "moving/subtracting a bedroom from one unit and add it to another unit in a duplex". 

Would like to 1031 the cabin and assume loan on house but my monthly income is child support $1137 for 1.5 yrs and a lame income of $800/month.
