For the Monthly payment cell, the Excel calculation is =PMT(B2/1200,B3,B1).   

Both are excellent, but most importantly is to just network with the participants.  

If you aim to keep your purchase price + renovation cost below 80% of the after rehabbed value, its an excellent way to gain equity.Since my property was also a duplex, I was able to live close to mortgage free since my tenant paid 90% of the mortgage and taxes each month.

I owned a condo in this same area and was experiencing excellent returns.

@Hector Naranjo I'd suggest even before paying for any tools, Create an excel spread sheet that factors in all of the expenses i.e. repairs 5%, Capex 10%, Vacancy 7%, Taxes(get from assessors site), Insurance(get quote from broker), management 10%(even if you are self managing), landscaping/snow(depending on market) and utilities. 

If you go with Buildium however, I will give set you up with our rep, who will give you excellent service, and you will get a 15% discount for 12 months (no strings attached, we do not receive any compensation for this). 

So definitely remember to ask around any agents if they ever had any properties that just simply never sold, never know if you could negotiate some excellent terms and find a way to make the weak points into gains for you.

Hi TeahjsiaHope you're doing excellent!

It is important to enforce the rules if you want them to remain enforceable; so you should absolutely address the smoking to retain your credibility, if nothing else. 

Excellent credit.
