Closing deals and being sure you are able to market yourself as a credible investor/owner/operator. 

It is excellent that you are seeking real estate investing advice at such a young age.

@Perry Farella Excellent.

Are there any credible websites or databases out there that people are using?

I easily track all my rental income and expenses for my properties with Excel.

ProForma Software – When conducting ProForma’s is there a software that is preferred to use other than an excel sheet?

Pro-tip:  @David Greene's book on BRRRR is the best thing I can recommend to you to build your plan and execute it with excellence.

Excellent ideas here, @Lucas Carl  I use a similar strategy for my LTRs in order to reduce the impending stress caused by tenants with the wrong mentality.Reading your post brought to mind a question I've never considered before:  are vacation rentals subject to Fair Housing Laws in the same way that LTRs are?  

Excellent read, thanks for sending it.Everyone I've spoken to has expressed fear of selling in this market.

I also have lots of time since the work from my 1099 gig will always be done remotely, plus one deal under my belt with decent cashflow and excellent tenants.
