There is a free version that allows you to do the planning, analysis and estimating that I would recommend you try before deciding to purchase the full version to see if this meets your needs. 

My recommendation would be to engage an investment property focused realtor (not a general residential realtor) and let that person guide you through the process from pre-qualification to market/property valuation and selection. 

If you are new and don't have a clue, then I would certainly recommend them or some company that can guide you through things until you have an understanding. 

it's very difficult to manage from a distance,  if you decide to keep it, i highly recommend to higher one.I live in SC, when i lived in CT i managed my units, once I left I got a PM.

Any book recommendations will be very much appreciated. :) Hi @David Gotsill, @Tom Wong, @Benjamin JonesI am in Kanto and investing in Hokkaido.Agree with the comments PR and language are barriers to entry.

If I have some cash do you recommend clearing the loan or invest instead for next property with proper planning ? 

Again, definitely consult with a CPA - our team has a few recommendations if you are interested and I can DM you as well. 

CT isn't cheap so if you plan on doing it there you are going to surprised at how poorly you do. maybe in the suburbs I'm not sure but as much as I know people call us from CT and everyone is rich and has lots of money and things are expensive out there. build to rent is a great model. we build 3 story walk up infill and keep it to the residential side. 3 units is the most units before it's commercial and you need engineering, etc. check comparable and things liek that. we came up with this design a year ago and we sold 10 if you want to talk further please DM me happy to connect. there are some great build to rent conferences. we went vertical not horizontal with it to save on build costs and design to fit on any infill lot. this fits on a 3500 square foot lot. most lots in our area are 30x120 or 30x150. in miami where I live now they are 50x100 or so. but any infill lot we can pretty much get this one on. there are some great build to rent conferences coming up too that if you like this topic I'd recommend attending I'm sure you'd learn a lot.  

@Christopher Leet, I can recommend an excellent realtor who works with investors and is an investor. 

Highly recommend (I require) collecting first month's rent prior to handing over keys.
