Is it safe to assume that with rates much higher, that the target IRR is now in the mid to high teens?

Move-in, mid-lease, renewal/move-out, plus any other time we have severe weather or other concerns relative to the property's conditions and maintenance. 

When you see mid-50s and I think there was a 65k sales price, those are likely owner occ. 

But don't see enough near-term or mid-term upside to keep them if something better comes along elsewhere that I can transfer into. 

Should I just sell the renovated home and the lots and take the win, or manage the building of the duplexes and go for a bigger win over the mid-range (while taking on the risk that things go badly or the market shifts)?

On a pure investment scale a mid term or short term in the midwest (omaha, KC, etc..) may net you better returns.

I have an 800+ credit score and access to over $100k in revolving credit and much more than that in personal loan offers, but currently have less than $10k in cash reserves, which I plan to build back up to $20k in two months.My mom, in her mid-50s, wants to invest in real estate as a means to improve her retirement.

Should I just negotiate to only honor the existing rentals until Mid December of 2024 and rent it out for the last few weeks myself?

I think mid-sized GCs would be more interested in this type of thing.

Is it a mid term rental?
