As for the estimated income taxes, there’s no gain until I actually sell the house, at which point everything would be in COGS anyway—under your method or J Scott’s method—so I’ll know how much net income was generated and can easily estimate income taxes.

We dealt with rentals, flips, commercial, small apartment complex developments (~10 apartments), sport facilities, and a few government contracts.We are actually very open to different opportunities and investment approaches, but our plan was to start "smaller" with some cash deals in NJ (maybe somewhere in the area between Staten Island and Philadelphia, but staying in NJ), by flipping a few smaller properties and starting to generate some income.

My understanding is that a lower price to rent ratio may indicate a property’s ability to generate cash flow.  

The outcome of investing in 9121 Chesapeake Blvd has been positive, with the property achieving full occupancy and generating a steady rental income.

Rent out any bedrooms you aren't using while you live there to generate even more cashflow. 

The tenants power was shut off for non-payment and I need to put the account back in my name.Recently my HOA sent me photos of my rental townhome with a gas generator running in the yard and the electric meter missing and shorted out.

It's smart if you plan to hold the debt and can generate cashflow, like any other loan.

A DIY cost segregation study will likely give you the report within a day.These studies are generated by completing a questionnaire that was created by engineers.Best of luck.

But, I would recommend hiring an REI-savvy Bookkeeping Professional one day so you can focus on other higher revenue-generating tasks.

If you scale in the future, you can upgrade, but now you just need something that works and generates reports and takes auto payments.
