I would look into the laws in your state regarding asbestos.Generally asbestos is not a problem unless it is disturbed.

We discovered that all crawl space vents had been sealed, leading to severe moisture buildup, extensive mold, and damage—now also affecting our tenants’ health.We need guidance on:- Is the home still safe to live in after opening the vents and potentially disturbing black mold?

A HELOC might offer more flexibility without disturbing that great underlying rate on your entire mortgage balance.

All depends on the size of the soil disturbance whether you need to file.

Try not to disturb anyone living there.

Given that your properties have substantial equity, a Home Equity Line of Credit (HELOC) is indeed a strategy worth exploring—especially since you want flexible access to capital without disturbing your current low-interest first mortgages.Traditionally, HELOCs are easier to obtain on primary residences, but they do exist for investment properties, including in Florida and Texas.

Why disturb the tenants unless youre willing to pay a price the owner is willing to sell at?

The previous owner had a signed lease with the following agreement of:1“In the event of a foreclosure, sale, or transfer of Premises…This lease shall remain in full force and effect, and Tenant’s rights and obligations hereunder shall not be disturbed or modified, except as provided in this Lease.”I want to know if it possible to modify/change these terms?

@Bruce Woodruff They want an accepted offer before the showing, to minimize disturbance to the tenants.
