I do want to insure it sells and I dont lose money on the deal.

For instance the cost of insurance there is super cheap compared to where I am.

I feel the second a huge storm hits, your insurance company will be your best friend and you will be out for a long time.How do you manage owning a rental property in shore towns, dealing with water and freak actions of mother nature.Thanks,Cody

When your cash buyer is rehabbing a house it can last 3 to 6 months, there are costs to consider for the duration of the rehab, things like property taxes, utilities, insurance.

Is there any type of insurance backing?  

With all that now I’m getting the ac don’t work again so I send out a ac tech I explain to them the the tenants are claiming that the ac isn’t cold enough that the Edison guy that took off the summer saver box off the ac fan told him the ac needs a Freon boost I’m really  now the  Edison guy is a ac tech the ac was running cold now it’s not working .well the ac tech did a leak test ,pressure test and said it was fine  but it looks like it was tampered with he also said if there was a leak there wouldn’t be Freon in the system still so I payed him to fill it up  since there was  few pounds of Freon still in the system he also asked me when was the last time i serviced the ac  I told him about a year ago .he said that long ago if there was a leak  there would be nothing in the system so after paying a few hundred dollars ,now I get another call saying the ac is blowing hot air .so I send the ac guy back  .the same ac guy said looks like it’s been tampered with.so now I decide to pay for home warranty insurance after the second repair and now  the tenants threatened to sue me.for my fist rental this is a bad experience of tenants trying to scam me and the plumber his freind doing fraud.i later called the water company again spoke to the manager this time explained what going on.he said just tell the tenants to call and give a one time to talk about the bill that I don’t have to be on the account so i did they refused again.

The new name on the insurance policy alerts the bank of the change in ownership.

My husband has stable job for over 10 years, but makes about 30% more doing side jobs under the table.
