However, please be careful if you go this route!

I have been investing in philly for quite a bit now and have started with the househack route and have properties in multiple areas of the city and surroundings.

Looking forward to hearing your thoughts so I can understand what is the favorite route in this area!

I'm sure there are strategies to mitigate that down the line when that time came such as a 1031 or something along that route?

Investing as an LP in a syndication is another route. 

If the liens are excessive then the tax foreclosure auction will be the best route as it wipes out other junior liens.

I’ll look further into the “subject to” approach and review the article you shared to better understand the potential risks and strategies.Gaining a seller’s confidence is definitely something I’ll keep in mind if I pursue this route.

There is alot of opportunity to househack even if you do not go the MFR route.

Which is why I go the section 8 route whenever possible.

It's not easy though and you'll need to really do your due diligence if you decide to go that route.
