What's your vision for your real estate future? 

Or if they want a high-interest rate, and your numbers will not work at that interest rate, or if they really want a crazy high price where it will be difficult to cash flow and refinance in the future.

I have done this a few times myself and have a few basic recommendations:1) Make sure the seller owns the property free and clear and that it's very clear to both parties whether the arrangement involves a deed of trust or contract for deed2) If a balloon payment is involved, be sure to assess your ability to refinance and make that balloon payment in the future- optional extensions can help manage this risk3) Understand the tax implications if the interest rate is notably above or below market rates4) Get title insurance! 

I think the combination of fed cuts, insurance carriers slowly coming back, population/job growth being steady, future new supply dropping off, and a few other things bode well for rental properties in the coming years.

To a future reader who comes across this same issue, what did I end up doing?

My wife and I own and manage 5 units as MTRs, and while it is certainly doable to manually update calendars across all the platforms (don't get me started on the deficiencies of iCal), we are looking to build a good foundations for future scaling as things are going well. 

I build tiny cabins near Houston and do STRs but I am in the process of building a tiny home LTR community in the future.

It's the spread between the purchase, ARV, and future cash-flow (lunch money). 

By asking us to fund repairs and then recoup them from future rents.

Don't listen to a brokerage pitch, they are all generally the same - our marketing is excellent, we are the leader in the area, look at our website and partnerships - they all have that.Cloud brokerages, in general, are better for independent self-starters, but the con is you will be on Facebook Workplace trying to network and won't have an office to go to.
