1. Are there any formulas you guys use to determine if something is worth while from cost - rent ratio?
1% and 50% rules are good for a newbie. I would look for more turnkey investments. You don't want to have to renovate to rent.
2. Anyone familiar with either city and recommend any areas?
Where are these 250k houses in Philly you speak of?! I dont know the area that well but I have family in the burbs in a 500k house that I dont even think is very nice.
3. Any reason to buy a duplex over a single townhouse?
Duplex > SFH I always feel you get some economies of scale, and spreads your risk.
4. Thoughts on rental vs REIT?
Do you like getting your hands dirty and fixing things? Do you want to do your own management?
6. What do you guys use as to determine what you can get for a property in rent to attain the 50% and 1% rule? Do you just look on Trulia for what surrounds rentals are going for?
That's a good start yes, but often they are already rented so you know you can get at least that! Again Id be looking for a turnkey property wtih tenants in place, this makes thing so much easier if you are just getting started.
Houston house? Did you move from there and rent out your existing SFH? What are the numbers on that? It would make me itchy to have a rental I could not drive too.
Good luck and happy hunting
There are lots of townhouses available in the suburbs of Philly that are good rentals in Blue Bell, Conshohocken, West Chester, PA
On the Houston side, we have a lot of family down there and visit 4-5 times a year. Its a 2 bedroom condo in a rising area so its appreciated a lot.
