I would hesitate to say 1-2 years to rotate out but closer to 5 years, and ideally I'd try to get the downpayment higher to at least 10%.I understand your areas though-- they're expensive.

However, I should note that this tenant has been late paying rent several times recently, which has added some strain to the landlord-tenant relationship.How would you approach this situation?

I would guess many government workers are renters like law enforcement and state department as they rotate in and out of the field offices to DC.

This is due to the strain on cash flow from the higher rates in investment properties.

Depending on local regulations, you can mix up STR/MTR/LTR. 2) Get systems in place in those exact cities; 2 PMs preferably via NARPM, 2 high quality inspectors, and rotating book of handyman, 1 lawyer, and a credit union contact for leverage along with investor friendly nationwide lenders.

I've head from others who went this route and had to pay before delivery which caused strain on capital because they couldn't complete draws in the same manner as stick built construction. 

Also I have seen a few listed due to divorce....I wonder how the STR strained their marriage.

There is evidence and provable data that the earth rotates the sun.You have no actual evidence that what you are saying is accurate.

Once a month may be difficult for some borrowers and lead to strain on advancing the project.

Johnson City could be a great spot for STRs, especially if you focus on hospital staff rotations, visiting professors, or traveling professionals, which would balance out any seasonal dips in tourism.For STRs, consider targeting weekend travelers exploring the Appalachian Trail, Boone Lake, or local festivals.
