I use their app for rent collection now and my tenants pay me rent every month in the app so that I can track rent roll and other expenses and incomes related to my property. 

All too often, we see incorrect rent rolls, shoddy bookkeeping, and a variety of other factors impacting CAP rates and the reported NOI. 

and want to make sure that I am keeping the ball rolling in terms of investing.

With regards to getting the ball rolling and acquiring new business/clients, I would start with the most basic activity - Role playing!

Then refi after your rehab and get the BRRRR strategy rolling..Good luck!

Things are rolling and the outlook is very good.

We did 5% down with closing costs rolled in for a total purchase price of $325K, the principal is roughly at $297K now, on a 30 year fixed @3.875% w/ PMI – Zillow/Redfin estimate $355-385K for a sale price.I went through a process of looking at condo/SFH comps with a local realtor/developer and his advice was to list at $365K and expect it to sell at around $370-375K.

The recent yield curve inversion shows that other factors also play a roll.

When i have a rental property, after i deduct the deappreciation, repair costs, mortgage interest and such all of the income from the property it self is deducted fully, does any extra amount of deduction roll over to deduct any of my W2 income?

Once you get rolling you can always tweak and adjust it to meet the needs of the market.
