Quote from @Isuf Aruci: i live in the NY area and would love to build a house or a mid apartment building. but the land search is very very difficult. also lets say i found the land, where would i get information and see if its buildable, also how do you calculate a land to see if its worth building or not.   

I’d have a better picture by sitting down with someone at a bank, but I did a calculation online and the new loan on cashing out $130k would still be covered by the current rental payment.

We have quite a few resources here such as our STR Calculator, STR Newsletter, and our bookstore which has "Short-Term Rental, Long-Term Wealth" that is excellent. 

I am 100% real estate development in my business so these are calculations I need to make all the time.

Sorry for the following Contrarian advice, but you're not a 5 year old so:The only reason to buy a personal residence (Home) is because someone is forcing you to.Usually, this person is called your Spouse (which is Latin for someone who forces you to make horrible financial decisions then criticizes you for them endlessly:)perhaps DON'T buy a home, just rent something affordable and invest the 20% or in your case 50% into the stock market (sp500 16.1% yearly return last 15 years, 11% last 50 years, 10% last 125 years)remember, your RENT is your maximum monthly housing expense, but your Mortgage is your minimum or starting monthly housing cost, it always goes up from thereI've, owned 2 personal homes, 100% appreciation in 6years on #1 and in 7 years on #2, (I timed our market perfectly both times), with 20% down and very low mortgage rates, but after honestly calculating all expenses, only made about 5-6% a year "investment wise".

Since it says you are new to real estate and sharing calculations, my experience is that a lot of new investors are spending a lot of time "modeling" and zero time actually seeing homes or multis or commercial properties in person.

Loans or lack thereof don’t impact tax calculations—only net profit matters.

Quote from @Scoop Schneider: 86k principle 7.5IR 360 months 800 credit score 1st position Put it on paperstac. my guess without dropping it into any calculator would be its worth $50-$70k assuming property value is above $100k

To start your first BRRRR investment, define your investment criteria, focus on submarkets with favorable cash flow and rehab costs, build your team, analyze deals using tools like BiggerPockets BRRRR calculator, and start small.

I also value cash flow with intent to fund a fix and flip as my first primary residence in the next 5 years.I have been analyzing local deals using the BP calculators, all of which leading to me thinking there is not a current future for me in my local market haha!
