@Haemi Jung Since you've been leasing the property for the past four years, you may be subject to capital gains tax on the sale of your co-op apartment, as it no longer qualifies as your primary residence.

But one of the best resources I've found is just reading, and listening to, as many books on the subject as I could find to really help deepen my knowledge and expertise.I actually just started listing to audio books over the last year or so and found a great app called Libby, that you can download for free through the Cleveland Public Library system and there's tons of great audiobooks on real estate and investing that I listen to when I'm driving and has helped me a lot!  

Am I subject to any tax or capital gains tax on that 100k?

The approvals are always subject to change at any point, but at least you would know what you're getting yourself into ahead of time. 

Hey @Tejas Paruthooli - This is for sure subjective and depends on your risk tolerance and budget. 

@William Coet, to add to Brian's comments:Banks, partly due to the regulations they are subject to, tend to fall low on the risk spectrum.  

Significant improvements excluded were homes that after the 2017 sale were torn down and built new, large renovations, additions added, extensive deferred maintenance addressed. 16 of the 152 homes were excluded leaving 136 to further analyze.Obviously there is some subjectivity in determining which homes had ‘significant improvements’.

Subject house math:-Purchase: $200k-Closing, rehab, to date carrying costs: $65k-ARV $400-425k-Rent $2900-3100-Taxes $9k a year-Insurance $1500 a year (Estimate)My math works out that if I refinance and pull all my money back out (LTV ~62%) I will have a total monthly cost (Tax, insurance, P&I) of about $2450 leaving roughly $500 cash flow assuming I manage the property myself.

Also if anybody has any suggestions on books to read on the subject of HELOC financing or any similar methods I would greatly appreciate those recommendations as well!

Memphis is a block by block city, so be careful to get your comps from very close to the subject property.
