However, have not saved as much as I would want to, though I do have some savings.  

If you offer some type of incentive to leave, she may choose that over going through an eviction process, which will save you a headache and worse damages. 

Don't buy so much house/duplex that you can't have a life and continue to save money. 

It gives you more leverage and saves a lot of wasted time in 99% of cases.

So to delay the process of saving for an eternity for the down payment on my first property I decided to apply for a HELOC.

I am asking how an experienced investor would follow up because I do not believe this property can be put under contract for a wholesale.Unfortunately I do not have the funds to fund myself a deal due to low income and putting any savings I had into starting this journey (possible mistake).

It has saved me at least $1,200 a year in federal taxes for the last 5 years.

I have listened to all of the podcasts here on BP and have saved up a nice chunk of change. $25,000 to be exact.

My question is, should I stop saving for reserves after a certain amount is met?

I was fortunate to have a savings fund my parent set aside for me I was able to pull out from after college.
