I am thinking about getting my license to facilitate my own purchases.

Title should be able to facilite payments if you want and have them handle LT escrow and will be just like any other transaction.However all that being said I would be more apt to figure out if can make this happen with the seller before wasting your time on it since you have a fixed timeline.Best of luck!

I recommend connecting with @Michael Schraepfer and attending the monthly REIA meetings that he facilitates.

Try utilizing a OTC or one time construction note or loan, its up to 726,200 loan amount so depending on your cost per sqft you could take that vacant lot you own (assumedly its free and clear) and use the equity in this land lot to facilitate your new construction and ADU build up to 726,200.Assuming 250 per sqft you can build around 2900 sqft of structures (SFR + ADU or total build out estimate).

We will likely be moving from the area, so we'd ideally like an active property manager to handle and facilitate all issues with the tenant/ within the unit. 

Your financial account structure depending on what your entity structure looks like; the size of your portfolio; your transaction flow; how you plan to grow your portfolio and making sure your books are set up to facilitate that growth; if you have any FLIPS those transactions are accounted for with a different method than your rentals; etc etc etcThat being said, as @Chris Seveney and @Todd Lennig mention above, I'm a fan of QuickBooks Online.

Quote from @Mark Brogan: a mobile home only heading we be nice since we are not interested in investing in mobile home parks or other commercial assets, what say you a,@Scott TrenchAre you saying that you want to invest in a single or handful of mobile homes, rather than in a mobile home park, and that the categories do not help facilitate discussion on this topic? 

But custodian will not setup such structure, you need to work with a facilitator company to structure your IRS-compliant vehicle. 

Also, it would be great if you could facilitate an introduction with the folks you mentioned above.

Things to consider when choosing a SDIRA custodian are customer service, knowledge, experience, and processing speeds, as they will be integral to ensuring that the investments you have chosen to self-direct are facilitated efficiently.
