Principal Paydown- If your loan term is say 20 years. 

First time buyer loan with 11% down.

As mentioned above look in the loan docs for reference to 'condition' or 'use'. 

Are there any lenders here that can finance a conventional loan without a full 2 years of work history?

I had a meeting with a lender about getting a second home loan.

Malibu allows it but requires a 15% "hotel tax" on the gross revenue.I would recommend looking out of state or underwrite the property as a long term rental in the event laws change.

A 0% APR credit card is a smart move for materials, but for labor costs, you might explore a private or hard money lender, especially since your loan term is only 3-4 months.

This means that when you sell the property, your adjusted tax basis is lower, which increases the capital gain you must recognize.Additionally, any accelerated depreciation taken is subject to depreciation recapture at a higher tax rate (up to 25% for real estate assets) rather than being taxed as long-term capital gains.So, while cost segregation provides significant upfront tax savings, it also increases your capital gains tax liability upon sale unless you use a 1031 exchange or other tax-deferral strategies.You can find your current tax basis by reviewing your depreciation schedule (Form 4562) and prior years’ tax returns, specifically looking at your adjusted basis on Form 4797 (for sales of business property) or Schedule D (for capital gains and losses).Your CPA should be consulted prior to making any decisions. 

as if it's more of a risk in midterms than in short terms.
