I am new to BiggerPockets and to BRRRR.We are two high-income earners, with two full-time jobs that put is at a gross income above $600K/year.

But I agree with an above poster that $10 psf in tenant improvement seems low, unless you can find a turn-key tenant to occupy that will require very little renovation.In DFW, for 2nd generation spaces, I've seen LLs underwrite at about $25-35 psf in expected TI allowance (subject to the lease terms and tenant credit rating).  

I am trying to go on maternity leave soon and may have to leave my job completely due to the boss not hiring anyoneto take over while I am supposed to be on leave soon!!

This may be challenging with both of you in full-time W2 jobs, but worth considering if one of you can transition to real estate part-time.Alternatively, the Short-Term Rental (STR) loophole offers another path.

It sounds like you've done a great job setting yourself up for options.

I ask because I've interviewed a number of general contractors over the years for my various real estate projects and am shocked at how the vast majority showed up to the job site to give an estimate in a vehicle that did not display their contractor license number or business name.Aside from this one issue, they'd often have great portfolios, long list of successful permits I could verify they pulled, great references, no complaints on their license, and had been licensed for over a decade.

Have some income coming in but not from a job.  

All of us have stable jobs and no other outstanding concerns.

For subdivisions, a civil engineer can help create plats and an improvement plan showing how utilities will be implemented.

So most likely, and please check me on this, I believe they will pay for the tenants rent for a year or so, but then, the tenant will have to get a job or go through a different government subsides program.
