Your credit, experience and liquidity will be the main factors - good luck!

I'm entertaining the notion of partnering on rentals so as to acquire leads that I would otherwise not be able to, due to lack of liquidity. 

I just don't see very many here in and around the Kansas City area that have any built-in equity from the jump; so, in general, if you're cool with having cashflow over equity and have a very long-term strategy, AND you have plenty of liquid capital in reserves for incidentals and such then by all means, give it a shot!

TSP is a retirement account. not very accessible car payments and personal loans are terrible revolving debtso you traded these two things for liquidity.

She told me that she did not want her apartment to be sprayed because her 20 year old daughter has asthma.  

I have been learning about REI lately as I have some liquid cash I was going to use to buy a SFH income property, which brought me to Biggerpockets to learn more. 

Profits and equity went one of three ways; paid back initial investor, were kept liquid or went into a mutual fund.

Rates may be a bit high but it beats killing your liquidity

after liquidating my long term rentals.

At the very minimum something like the Defense Tech Mk-6 stream spray.
