Yes you can do HELOCS on investment properties as long as it's not a multi unit.

Could be self inspection (photos) but it's not uncommon and most are done by third party inspection companies.

Also, I'm not sure how you're paying attention to it on the tax side, but the unit that you are living in's profit at sale is calculated differently than the other unit that you're renting out.Once you move out, that unit is officially available for rent so from that point forward, any profit gained at future sale will be calculated starting from that point and will be taxable.

My unit is located by Rose Medical.

Maintenance can also be a factor—while newer homes may require minimal upkeep, older units might need more frequent repairs, particularly for things like plumbing or HVAC systems.Some things to pay close attention to:Zoning and Permits: Check local zoning laws and permit requirements to ensure you’re allowed to place a mobile home on your land and rent it out.

Can anyone give me some advice pros/cons on having a single family unit with a pool as a rental unit.

Urban Lot Splits (ULS) allow you to divide a lot into 2 parcels, and Multi-Dwelling Unit Developments (MDUD) are allowed up to 2 units per lot.

Now, we own 65 apartment units and 80,000 SF of commercial warehousing.Let me know if you have specific questions. 

Investment Info:Small multi-family (2-4 units) buy & hold investment in Bronx.

You can use this property to hedge any others that you add that may only cover themselves, or require supplement until they are paid off.HOWEVER, if you have decided that your goal is to use Real Estate as a stepping stone to build wealth by upgrading the property you hold each time (condo to house, house to 4-plex, 4-plex to 8 unit, etc) then I think you are right to sell now while you think the property is at the top of it's appreciation.It will be hard for anyone on BP to tell you what to do as we don't know your goal.You are right.
