@Phil SheltonYou would need a civil engineer to provide a drawing to get submitted to zoning and get a permit if it passes zoning is most common This also depends on the road - if it’s a state road forget it as it will take a year to get approved and cost a fortune - if it’s a local road process not as cumbersome but don’t expect this to happen quicklyIn some instances you may have to prepare sight distances etc to make sure it’s safe to add a curb cut

These options could provide flexibility with your upfront costs and monthly payments.Expand Your Search Radius or Property Type:If you’re set on a single-family home, you might find more affordable options by expanding your search to nearby areas in San Diego County or by considering properties that need a little TLC.Partnerships:Partnering with another investor or family member might be a way to pool resources for a purchase.

To apply cost segregation to your 2021 taxes, you need to do it at any time before you file your taxes, not before the New Year's champagne toast.Home office.

I would still use quickbooks to track the finances in that account snd all rental associated finances (we use it to track are personal finances also). by the way it is worth the cost of paying someone good with quickbooks to do the initial setup.  

2.What are the best and most cost-effective solutions for managing this potential long-term issue?

Hiring a lawyer sounds expensive, but it is way cheaper than hiring a amateur (in this case yourself) who costs you money and provides no results (and then you need to hire a professional anyway).My personal philosophy is to "do it right, or do it twice" and its way cheaper to do it right once. 

What is your average work order cost for the owner?

Determine the most likely sales price of the build (factor in the cost of the land also) and include all selling costs to arrive at your net profit and ROI. 

Going private money will already cost you more $$ in closing costs, points, etc - but they should ONLY collect $$ if the loan closes.

When considering refinancing, also factor in the closing costs of the new mortgage to determine if it actually helps you.
