This is being very conservative with all the numbers, if anyone is interested in specifics I can provide in a pm.Super excited, as now I have a target AND a plan for my goal.lets ****ing go.

If you achieve the ideal BRRRR with zero costs, you might as well perform it in a high PSF location (as high as you can tackle with conservative reserves).My last rehab was on a property that was almost $2k psf.  

My worry is that while I am clear on the risks (extended timeline to get a tenant in, and expensive buildout) that I am not being nearly conservative enough - do I risk this thing sitting empty for a year, or years, and finally renting well below my implied rate? 

.: BRRRR have some items that flips do not (plus most of the flip items):- refi appraisals in my market are conservative.  

The software is going to be very conservative with your write-offs.

Recessions have a good way of making anyone's conservative assumptions look not conservative enough.  

It depends on the lender but at a min they must follow TX SML or lending laws in the state in order to compliantly lend in TX, on whether choose to apply this guideline to all types of occupancies or transaction types (non owner investment, second homes/primary residences, etc)80-85LTV on rental properties is only on the purchase for fannie/freddie loans but on rate term refinances its max 80% and cash out max 75% for 1 unit and up to 70% for 2-4 unit cash out conventional.On HELOC's and rentals are up to 70-75% depending on the HELOC investor or product.Its good to distinguish between what the lenders are willing to do and for which product and also these loan products must abide my state law as well as an additiona layer of "overlays," on top as well (whichever is worst / most conservative).

When I do it for me and my clients, we go very conservative to give better expectations of the transition process, than if it goes better, great!

Also, try to find similar rental units in the same neighborhood to compare to so you have more of a rent range/conservative approach. 

just don't do a lease. as others have mentioned, this forces the buyer of the property to take over the lease (if its even allowed/ they qualify) and it certainly does make the property a little tougher to sell. i'm also doing a house hack, and here in CA, its made a world of difference for me. the bulk of our energy usage is in the summer when we want to run the a/c. my bill stays a constant $228/mo (i pocketed the tax credit and simply financed the panels after that grace period). instead of getting an $800 bill in the summer months, we run the a/c at a constant temperature 24/7 on auto, stay comfortable, and i typically get a little bit coming back at the end of the year. don't expect to pocket this "little bit back" by being conservative with your useage, it sort of is a use-it-or-lose-it situation... i think i got $54 back this year.
