At least that way you can feel confident that the additional leaf guards etc will truly prevent it from happening in the future. 

And, I'm closing a commercial property that requires $300K down and the closing date is Oct 15.If I pay the income tax, I will not have enough fund for downpayment.But if I don't pay the tax, I may get a tax lien on my company which may prevent me from getting an approve for the mortgage plus I need to pay around $10K penalty.And, if I get a $200K loan, they may put an lien on my company and potentially prevent me from getting a mortgage too.So, what should I do now?

If it is a retention pond, then it is permanently holding water to prevent downstream flooding. 

Create a penalty/fee that prevents loss of income.

@Kevin Hausfeld   Nothing would prevent you from building another home on it, assuming there are no zoning/building restrictions for 2 homes on one lot, but you couldn’t get a loan for it.

Simon, Here in FL its much easier for us because we know a few things:1) The U.S. is severely under supplied in housing units. 2) Tons of people are moving to Florida everyday which makes point #1 even more drastic for us. 3) Interest rates are preventing people from selling their homes, because then they would need to re-trade for a higher interest rate buying a new home, which is creating even more housing demand.So with this knowledge, now we move to more market specific data, which is what I talk about in the original post.If a market shows decent growth and demand, then it all boils down to the numbers.Its important not to forget about any costs though.

Or outsourcedIf they've had deals that have lost money, why did they lose money and how do they prevent that again from happening in the futureIn place cap rate the property is being bought atIn place cash flow from day 1 the property will have (based on trailing financials, not projected)Debt - fixed or floating?

If your systems are failing, I would be looking at your preventative maintenance process.

(referrals would be appreciated)I suppose the settlement agreement executed Feb 6th prevents me from assigning the mortgage in his name to the probate estate… However, I’ve read that since he’s deceased I could potentially assume that mortgage at the 1.6% that’s locked in… if I knew or if that was the case I certainly wouldn’t have sold… Purchase $1.4 2021Mortgage $260k @ 1.6%Improvements $187kSale $1.985 2024Commission total: $3.5%
