Hi, Are there any lenders offering HELOCs or second mortgages on rental properties with equity?

That might be our only true recourse.I don't know what State you're in or if you used a builder contract or the standard State contract form.

Some transport companies have house kats that can get off the road and onto the site for an additional charge or you can hire a third party if the access from the road is limited.  

Since your lot is already zoned RS3, you can (by right) build a new SFH or 2-flat.

I think this arrangement is better than nothing or me taking her to court to only get the land back. 

Quote from @Sergio P Ramos: @Jay Hinrichs did you demo it yourself or hired a company to demo?.

They are billed as "a scientific approach to single-family rentals" and use "institutional grade property management," which usually means they are a tech company in real estate and likely either don't have the existing property management relationships in each area or you chose an area where they don't have enough units through Roofstock for the PM they chose to care.

The ability to turn single-family lots into duplexes or even split lots for separate units can significantly boost rental income and property value.

Off by a day its like a$250 or $500 fine.

I’d love to connect with you or other investors in the area.
