Two of the biggest challenges I face are that I’m not very liquid at the moment, and the Seattle area is extremely expensive.

Quote from @Fernando Martin-Gullans: Hey y’all, I’m a retail investor with 2 SFH rentals worth a combined ~$650k looking to utilize some of my stored equity to buy more out-of-state properties, but I’m not quite sure how best to proceed given that my interest rates are incredibly low (leaning me away from refinancing) and neither property is owner-occupied (which I believe prevents me from using a HELOC).

A full box of 250 dryer sheets, a big Tide liquid and fabric softener (liquid).

Let's assume that the neighborhood is a C class and the median income of the city is greater than 3X of the market rent.Here are some of the considerations I've come up with so far:- Units are in need of renovation and capex is too high or not available- Unit quality is not the same as market - Seller is worried about losing tenants due to increase- Vacancy rates are high or filling units have been difficult- Rent increase would take multiple increases over multiple lease periods to get to market rate if seller is trying to retain the same tenant- Seller inherited property and just want to liquidate- Seller needs to liquidate quickly (financial burden, sickness, quick exit from land-lording)It seems like I might be missing a warning sign about a deal if they are selling with current rents that are under market; but again, this seems to be most of the properties I've underwritten.And in the same vein, what should I be worried about when purchasing a deal with under market rent with the intention of raising them after purchase. 

If I were in your shoes, I’d look at the BRRRR strategy (Buy, Rehab, Rent, Refinance, Repeat) to stretch your liquidity while building equity and cash flow.

Cash out refi only if the rental income significantly exceeds the monthly payment and you want liquidity to invest elsewhere.2.You can maybe do a HELOC if you want a smaller loan that doesn’t involve refinancing the entire house.3.

Though it may cash flow well based on their current debt service, when you compare the income it produces to the equity they have is it actually even a good investment for them from an ROI perspective or would they be better off liquidating and redeploying?

There was a recent webinar, bottom line, it looks like Darryl Heller sold off many of the ATMs, didn't pay the people who put the cash in them, didn't pay the stores that have them on site, isn't providing information to David Zook's team that the court has ordered and is racking up something like $50k+ a day for not doing so...it is a complete mess and seems like there are only a fraction of the ATMs that might still be producing money but the company hired by Zook to get their hands around all of this is running into many roadblocks because Heller's team isn't providing info. 

The BiggerPockets store has books that will teach you how to analyze properties.

Anyone can buy a stable senior income fund like FLBL with the click of a mouse and no liquidity or complexity issues.
