Doing some due diligence on a private lender based in Lubbock, TX. 

Its all about finding a group that will work with you proactively and provide you with a strong ROI based on your current fact pattern.

I have 6 single and MF properties with a 7th under contract and have made some tax and business development missteps that they are helping us to manage, plus advising in setting up our entities and accounting based on a deep fact-finding inquiry on their part.

That way you can understand local pricing/demand/tenant base along with grasping the mechanics of a real estate transaction. $50,000 would be plenty for a 3.5% down FHA loan (ie. househack a duplex/triplex), or a $200,000 single family via an investment property loan.

There are not a ton of rental properties in the area but the price seems decently competitive based on the few other townhomes I see on realtor.com The photos in his listing are not great. 

AirDNA provides yearly revenue, taking into account occupancy and different rates based on a season.

(used to be 25% nets )  Again you can buy a duplex that will have about 12- 13k NET income on gross of about 20k, with an all in PP of 108k,,,, thats about 12% net based on a cash purchase.

I just have built up my rental base in the core US markets and used that cash flow to travel/surf in PR.

If you are maxing out with the W-2 associated plans, your Solo 401(k) would be limited to accepting employer profit-sharing contributions based on your real estate commission earnings.There are several solid professionals who specialize in Solo 401(k) plans here on BP. 

Just be mindful of any PPP if you are planning to refinance with a DSCR based loan.
