Hello everybody,I found a property with extensive fire damage to it.

Once all the furniture was out of the house, I quickly realized the renovations I planned on doing would need to be much more extensive.

Aloha,First, check the laws for your jurisdiction...not all allow charging tenants for water.Submetering a multi unit will require either extensive re-plumbing or individual flow meters at each fixture, which will likely be costly.You would need to wait until renewal of each tenants agreement to make such a significant change in terms, and likely with 30 day or more advance notice.

When I'll do the extension of the leases, which will be M2M is it that the right time to ask for the move in fee?

I have extensive experience there doing 1ks of repairs and rehabs, NEVER hire anyone without a team that has a mutual benefit, again it will not end well 

I have done some research on the net and I am asking the Heirs to find the last statement and ask for an extension.

Replace unit for sunroom that is an extension of the patio or work on doorway and insulating?

Any other time I would say take it just from what I know but right now with the extension of the eviction moratorium to September(?)

Now if someone is paying cash you could possibly get a  higher cap rate with low lease years remaining and work on a long term extension and then cap rate compresses again for a higher resale value.As for commercial foreclosures I only have those types of properties where accredited investors can invest in my syndicate as a sponsor.

If a property is worth maximum $40k, I'm going to go out on a limb and say that the owner is probably not an attorney or someone with extensive real estate/pricing/comparative-market-analysis experience and doesn't know much about pricing properties or executing deals.
