So many intellegent and supportive individuals on here, you will get out what you put in.

I am wanting to purchase a condo in the St Pete Beach (preferable Treasure Island) market post hurricane(s).

Moreover, it allows you to set the terms of the lease agreement according to your preferences, which can help prevent misunderstandings and disputes in the future. 

Looking to either sell individually or as a package to an investor.

Preferably looking for properties under $200k, but up to $300k.

If not for you and you prefer the traditional route, I would explore potential "up and coming" markets such as Acworth, Cartersville, and Douglasville, where the price-to-rent ratio is a little more favorable, and growth is apparent.

Specifically, I am looking at partnering with an individual who owns securities (stock and mutual funds) having them take out a line of credit against their portfolio (SBLOC) at a low interest rate, and using that to purchase properties rather than using a mortgage.

Our strategy is to buy out of shape properties and rehab them back into shape, so a GC with experience in doing extensive renovations at once would be preferred.

Current individual stock portfolio (non-retirement accounts) with holdings that might be volatile in the next few years (big tech & big oil). $51k is about 17% of the portfolio and gains on the stock holdings are already 100-200% (long-term).

Maintenance and potential repairs will also require a long-term financial plan and setting aside a contingency fund for such expenses.The steady cash flow, appreciation over time, and tax benefits can make a meaningful difference to your wealth in the long term, especially with the principal paydown on the mortgage.However, if managing the property from a distance feels too burdensome, or if you’d prefer the certainty and flexibility that comes with having less debt (especially given the high mortgage rates), selling and using the $100,000 in equity to reduce your loan for your next home may be the smarter move.
