There are lots of experienced property owners, lenders, real estate agents, attorneys, tax experts and more here so don't be shy to ask questions and I'm sure an expert in that field will be able to help.

My question: In the original lease it states to make payments via check or money order to the Property management office.

Every dollar made was put aside and then used to reinvest in another property.

When researching rental properties for potential investment. 

We've been honing in on a pretty good development/investment formula that is working for us where we buy an existing single or multi-family house that can be improved or easily split into smaller units, and then we also add small new construction units to the property (townhomes or duplexes or cottages) and, generally, we rent them all out (though we have sold a couple of single family rehabs and we may sell the units in our next big project...

Unfortunately having title issues is one of the reasons that sellers are sometimes willing to do seller financing simply because they know mortgage companies won't approve without proper title work and title insurance so they have to be more creative in the ways they sell but that can be risky for you as a buyer.If you do seller finance I recommend having very specific terms on HOW payments will be made and accepted and using a professional service like https://www.agecroftcapital.com/ for loan management in the case of any disputes - just my personal rec, not sponsored by BP though I do work for BP :)

Property is used as a short term rental.

I currently self manage my properties using Buildium and I love it especially the resident portal and ability to accept ACH rent payments.

@Jesse Herndon and @Troy Biggs, We are in the process of selling our primary residence and will be full-time RVers as we explore the US for the next year (or more :)  We currently own 4 rental properties and I am wondering if you can offer any advice on liability insurance. 

As well as a better ability to find properties?
